The Planet Jupiter – Planets In Our Solar System

Planet Jupiter

The Planet Jupiter - Planets In Our Solar SystemJupiter is the planet in the fifth position from the sun. This is the massive and huge planet in the solar system. It is filled with hydrogen and helium. It has a different trace of gases.  The planet Jupiter has dozens of moons that it appears to be a miniature solar system and it has a strong magnetic field. There is a great red spot in Jupiter.

  • Orbit:9 Earth years
  • Diameter: 86,881 miles (139,822 km)
  • Day:8 earth hours

The Planet Jupiter is the largest planet, named in Roman mythology after the king of the gods. Jupiter helped in revolutionising as Galileo discovered four large moons of Jupiter’s, the Io, Ganymede, Europa, and Callisto, representing as Galilean moons. These celestial bodies were circling Jupiter and not the earth.

Jupiter is 80 times massive. The atmosphere is identical as the sun comprising of helium and hydrogen, besides it has four large moons and also smaller moons around it in the orbit that Jupiter maintains an individual miniature solar system. The volume can hold nearly 1300 Earth’s.

The planet Jupiter bands are colourful arranged in light zones and dark belts travelling 400 mph. There are white clouds made of frozen ammonia crystals and the darker clouds include chemicals appearing in the belts. Blue clouds are visible at deepest levels, while the cloud stripes keep changing.

The Great Red Spot

The great spot in Red colour is the extraordinary feature; a hurricane-like giant storm seen for over 300 years. This red spot is the widest and thrice the earth’s diameter, while its edge spins around the centre counterclockwise at 225mph (360kph) speed. The storm colour varies from red to brown due to the ammonia crystals featuring phosphorous and sulphur in the Jupiter’s clouds. However, the spot shrinks and grows each time, while sometimes it appears to completely fade.

The magnetic field of Jupiter is the strongest having 20,000 times of Earth’s strength. It traps in its intense electrons belt the electrically charged particles, while the other electrically charged particles keep blasting the rings and moons of the planet with a radiation level over 1000 times. Jupiter’s magnetosphere comprises of particles and fields’ swelling out nearly 600,000 to 2 million miles towards the Sun and its tail extends to 600 million miles behind the Jupiter.

Jupiter spins faster on its axis taking under 10 hours to complete a turn in comparison to the Earth taking 24 hours. This rapid spin makes Jupiter flatten at the poles and bulge at the equator. Radio waves of Jupiter are strong to detect on earth when the Jupiter’s large moon, lo, passes the magnetic field of Jupiter in certain regions.

The Planet Mercury – Planets In Our Solar System

Planet Mercury

The Planet Mercury - Planets In Our Solar SystemThe Planet Mercury is the closest planet to the Sun. With virtually no atmosphere, the planet has some really harsh conditions with temperatures rising to 840 degrees Fahrenheit during daytime and fall to hundreds of degrees on the negative scale during night. Mercury has almost no atmosphere that can absorb meteor impacts and hence, its surface is strewn with craters.

  • Orbit: 88 Earth Days
  • Diameter:3,031 miles (4,878 km)
  • Day:6 Earth days

The present name given to the planet Mercury is that of the Roman messenger god. This is due to the fact that it circles the sun faster than the other planets. The planet has been named differently by different civilisations. The Sumerians knew about this planet around 5,000 years ago and they associated it with their god writing, Nabu. Mercury is known as a morning star as well as an evening star. However, Greek astronomers knew that both names referred to the same astronomical body.

Smallest Planet

Mercury is the smallest of all planets. Physically, it is only slightly bigger than Earth’s moon. Due to the absence of a significant atmosphere, the planet faces some of the worst temperatures in the solar system and also is hit by asteroids and meteors. Around 4 billion years ago, Mercury was struck by an asteroid that was roughly 60 miles. The impact was equal to the explosion of a trillion one megaton bombs. The resulting crater is today known as Caloris Basin. It is believed that a similar impact may have resulted in the odd spin that the planet follows presently.

Despite being the closest to the sun, water ice has been discovered in craters around its north pole. Certain regions may be permanently shaded from the sun’s heat aiding in the formation of water ice. The southern orbit has also contained ice, but this has not been validated by scientists yet.

The planet Mercury is the second most dense planet after Earth. It is a core of around 2,200 to 2,400 miles in width. The outer shell of the planet is only 300 – 400 miles thick. This fact is a mystery for scientists till date.

It was recently discovered that the planet Mercury possessed a magnetic field. Due to its slow rotation speed (59 Earth days), the planet was not expected to possess one. The presence of such a magnetic field suggests that its core may still be molten, although solar winds may dampen some of the magnetic field emanating from the planet.

 

 

Planets In Our Solar System

Planets In Our Solar System

Planets In Our Solar System - (Planets In Our Solar System)Planets in Our Solar System, A solar system is essentially a star and the objects that orbit around it. Our solar system consists of the Sun in the centre around which eight planets, a dwarf planet and some asteroids revolve. Our solar system is in an outward portion of the Milky Way galaxy. Let’s have a look at the planets in our solar system.

The planets in our solar system were discovered after astronomers followed moving points of light among the stars. Mercury, Venus, Jupiter, Mars and Saturn were discovered in a similar manner, while Neptune, Uranus, Pluto, the Asteroid Belt and the moons of many planets were observed only after the telescope was invented. The discovery of the dwarf planet Eris led to the discovery of other dwarf planets. Several space probes were sent out in space to further explore the solar system and are being continued today.

Solar System theorised

The solar system is theorised to have originated from a giant rotating cloud of dust and gas known as the solar nebula. This nebula collapsed due to its gravity. It spun faster and was flattened to a disc. Most of the material from this nebula moved towards the centre and formed the sun. Other particles collided and stuck together to form planetesimals (objects that are the size of asteroids). Some of these planetesimals combined to form comets, asteroids, moons and planets. The solar winds were very powerful and swept away lighter elements such as helium and hydrogen from the inner planets. The solar winds were much weaker in the outer planets and hence, they are predominantly made of helium and hydrogen.

Planets in our Solar System

In the order of their distance from the Sun, the planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. In the year 2006, The International Astronomical Union classified Pluto as a dwarf planet and it is effective, not included in this list. Apart from the planets, it also includes meteorites, comets, asteroids, a disc-shaped Kuiper Belt, a spherical Ort Cloud and a heliopause that is shaped like a teardrop. The solar system is estimated to stretch for a distance of 9 billion miles.

Planet Nine

Evidence for a new planet nicknamed “Planet x / Planet 9“was unveiled in 2016 bringing the number of planets in the solar system back to nine. It is estimated to have a mass that is 5,000 times that of Pluto and 10 times that of Earth. This planet x (video) is believed to exist between Neptune and Pluto. In any case, Pluto is the farthest object in our solar system orbiting in an elliptical and completely tilted axis.

The sun lies at the centre of our solar system and is by far, the largest object in it. It contains around 99.8% of the mass in the entire solar system. It provides light and heat without which life on Earth would stop. Most of the other objects in the solar system orbit in oval-shaped paths, with the sun slightly off centre from their paths.

Kinds of Planets

The planets in our solar system are of two kinds. The first kind is Terrestrial planets or planter whose surfaces are rocky. This includes Mercury, Venus, Earth and Mars. The other four are called Jovian planters because they are huge in comparison to the terrestrial planets and more importantly, are gaseous in nature. Jupiter and Saturn are basically called gas planets while Uranus and Neptune have more ice. A common feature is that all four planets contain helium and hydrogen.

Pluto also has solid rocky surfaces. But since it has been classified as a dwarf planet, it falls out of this list. The IAU defines a planet that can circle the sun without being the satellite of any other object while being large enough so that it can be rounded (by its own gravity) and must ‘clear the neighbourhood’ of other orbiting objects. The problem with Pluto is its small size and its odd orbit when compared with the other planets in our solar system. Most importantly, Pluto’s orbit shares space with other object belonging to the Kuiper Belt that lies beyond Neptune. Other dwarf planets are Eris, Makemake, Sedna and Haumea from the Kuiper Belt and Ceres from the Asteroid Belt that lies between Jupiter and Mars.

Comets

Comets are comprised of primarily rock and ice. They follow very long orbits that bring them closer to the sun at certain points. Some short-period comets are thought to originate from the Kuiper belt and complete their orbits within 200 years. Long period comets take more than 200 years to complete their orbits and they are believed to have originated from the Oort Cloud. When comets come very close to the sun, some of the ice in their central nucleus evaporates into gas which is carried outward, giving it a characteristic ‘tail’.

The Kuiper belt is long suspected to exist beyond Neptune and is estimated to house more than a trillion comets and some hundreds of thousands of icy bodies.  Beyond this lie the Oort Cloud, Heliosphere and Heliopause.
