Solar System Planets.

The Sun
The Sun is the biggest star in the Solar System and is located in the center of it. It is similar in terms of composition when compared to other stars. Its mass constitutes more than 99% of the Solar System. More

Mercury is the innermost planet in the Solar System which is why its temperature is extremely high and the atmosphere is almost non-existent. Mercury doesn’t have any satellites. It takes 87.969 Earth days for Mercury to complete an orbit. More

Venus is the sixth largest planet in the Solar System and is the third in line when it comes to the brightest objects in the night sky. Venus and the Earth are similar in size due to which they are often known as the sister planets in the Solar System. The planet does not have any natural satellites. It takes 224.7 Earth days for Venus to complete an orbit. More


Earth is the only planet in the Solar System which has life on it. Earth has only one natural satellite - the Moon. In addition to it, other satellites, artificial in nature, orbit the planet as well. It takes 365.25 days for Earth to orbit the Sun. More


Mars or the red planet was considered to be identical to Earth by a few scientists. A few years ago, they saw traces of life on the planet but this theory was soon proven wrong. Interestingly, the liquid form of water could be found on the planet during the initial years of the Solar System. Phobos and Deimos are two natural satellites of Mars. Its orbital period is 686.971 days or 1,88 years. More


Jupiter is the largest planet in the Solar System and there is a large red spot on its surface which is a storm that has been taking place on the planet for over 200 years now. Jupiter has 63 moons. The orbital period of the planet is 4,331.572 days or 11,86 years. More


Saturn has the least weight among the Solar System planets. It has four thick layers of rings and three thinner layers. The origin of these planetary rings is not known for sure. Saturn has 61 natural satellites with secure orbits and about 200 are being discovered. The orbital period of Saturn is 10,832.327 days or 29.66 years. More



Uranus is the seventh one among the Solar System planets. It consists of rings which are very dark in color because of which they are not too visible. The surface of the planet is covered with ice and rocks. The planet has 27 natural satellites. The orbital period of Uranus is 30,799.095 days or 84.32 years. More



Like Jupiter and Saturn, Neptune has rings made of rocks. Methane, water vapor, helium and hydrogen constitute the atmosphere of this planet. Not much is known about Neptune because of its large distance from Earth. This Solar System planet has 13 natural satellites. The orbital period of Neptune is 60,190 days or 164.79 years. More

Dwarf Planets

Each dwarf planet has a very powerful gravitational pull which is why they are small in size. They should not be confused with satellites or minor planets. Makemake, Haumea, Ceres, Pluto, and Eris are examples of dwarf planets in the Solar System. More



Asteroids are similar to rocks found in space. While some are as large as boulders, others are smaller than grains of sand. These small asteroids have a very weak gravitational pull because of which they have an uneven shape. More



Comets are very bright and are located towards the extreme exterior of the Solar System. Their tails are very bright and mainly consist of ice and dust. They can be found either in the Oort Cloud or the Kuiper Belt. More
