The planets have been categorized in many ways before, but now we can safely put them into three groups: the gas giants, the ice giants, and the terrestrial planets.īased on their size and composition, the eight planets of the Solar System fit well in these categories. Everything here formed at around roughly 4.6 billion years ago from the solar nebula. Every one of them is unique in their own way. Our Solar System is blessed with 8 planets. Venus is the hottest planet in the Solar System since heat cannot escape from its surface. Though Mercury is the closest planet to the Sun, it isn’t the hottest.
It would take around 24.462 Mercury’s to fit inside Jupiter’s volume. In comparison to Jupiter, it has more than 29 times the diameter of Mercury. Mercury is three times smaller than Earth. The smallest planet in the Solar System is the terrestrial Mercury.Jupiter has more than 11 times Earth’s diameter, and you would need 1.300 Earth-sized planets to fill its volume. The biggest planet in the Solar System is the gas giant Jupiter.Neptune, on the other hand, is the farthest planet from the Sun, and it makes one trip around it once every 165 Earth years. Our planet, Earth, revolves around the Sun once every 365.25 days – one Earth year.They all have different intervals in which they complete one orbit around the Sun. All planets in the Solar System revolve around the Sun.The gods were associated with these planets due to certain traits, Neptune, for example, is very blue and thus it was named after the Roman god of the oceans, in Greek mythology he was known as Poseidon. Except for Earth, all the planets are named after Greek and Roman deities.However, Pluto is now considered a dwarf planet. A couple of years ago, Pluto was also considered a planet and was the ninth planet of the Solar System.In order of size, they are Earth, Venus, Mars, and Mercury. Though they are the smallest, these planets are the only ones that have a surface. In the third place are the terrestrial planets.Coming into second place, based on their size, are the ice giants Neptune and Uranus.The biggest planets in the Solar System are the gas giants Jupiter and Saturn.The planets of the solar system are grouped into three categories, based on their size and composition: They are gas giants (2), ice giants (2), and terrestrial planets (4 – including Earth).
