One day on Neptune lasts 16 hours, while a year is equivalent to 165 Earth years, the longest of any planet. The most probable theory for the formation of the solar system is a) Condensation of a nebula of cold gas and dust into the Sun and planets b) Condensation of a nebula of hot gas into the Sun and planets c) An encounter, in which a Like Uranus, it is also an ice giant. Jupiter is a gas giant; it is … How to Remember the Order of the Planets in Our Solar System. In our solar system, the planets Jupiter, Saturn, Uranus and Neptune are more massive. Jupiter is the largest planet in the solar system at 139,822 km in diameter. This means that Jupiter is actually more than 28.5 times larger in diameter than the smallest planet, Mercury. Mars is less dense than Earth, having about 15% of Earth’s volume and 11% of Earth’s mass, resulting in about 38% of Earth’s surface gravity. One day on Venus is equivalent to 243 Earth days; thus, a day on Venus is longer than a year. It orbits a red dwarf star called Gliese 832.
