The biggest planets in the Solar System are the gas giants Jupiter and Saturn.Coming into second place, based on their size, are the ice giants Neptune and Uranus.In the third place are the terrestrial planets. Though they are the smallest, these planets are the only ones that have a surface. In order of size, they are Earth, Venus, Mars, and Mercury.A couple of years ago, Pluto was also considered a planet and was the ninth planet of the Solar System. However, Pluto is now considered a dwarf planet.The terrestrial planets are the smallest in the Solar System. They are part of the inner solar system, being the closest to the Sun. The smallest terrestrial planet is Mercury. Mercury has a radius of 2.439 km / 1.516 mi and a diameter of 4.879 km / 3.032 mi. It is three times smaller than both Earth and Venus. Marsis the second-smallest planet, ha...
The terrestrial planets Mercury – Venus – Earth – Mars, are mostly made up of rock and metal. These planets are very heavy and move slowly. They have a solid surface, unlike the gas or ice giants. The terrestrial planets have a central metallic core composed mostly of iron, with a surrounding silicate mantle. These types of planets have common feat...
Both the gas giants and ice giants are part of the outer solar system, being the farthest from the Sun. They are separated from the terrestrial planets by the Asteroid Belt. The gas giants are the biggest planets in the solar system. Jupiterhas a mean radius of 69.911 kilometers / 43.440 miles, a diameter at the equator of around 142.984 km / 88.84...
The gas giants are mostly composed out of gases such as hydrogen, helium, and they presumably have a small rocky core in the center. Both gas giants have over 70 confirmed moons, a lot more than the ice giants. Though both ice giants and gas giants have planetary ring systems, the gas giant Saturn has by far the most prominent ring system ever seen...
Ice giants are also gas giants, but they are so named because they contain less gas and are compositionally different than the gas giants. They are the farthest planets from the Sun, and though they are considerably bigger than the terrestrial planets, they are also very small compared to the gas giants. The biggest ice giant is Uranushas a radius ...
The ice giants have an interior composition that consists primarily of what astronomers call ‘Ices’. These are compounds like water, methane, and ammonia, and are so-named presumably because they are solid at cold temperatures. They, like the gas giants, don’t have a true surface and presumably have a small core at the center. They indeed have the ...
Both Uranus and Neptune are blue to the presence of methane.Uranus and Venus rotate in the opposite direction than the other planets, from East to West. Uranus is also the only planet known to rotate on its side.The biggest moons of Uranus, all of them, have surface areas smaller than the continent of Australia.The original name proposed for Uranus was Georgian Sidus – which means Georgian Planet, in honor of King George II, however, the scientific community didn’t agreePlanets & Deities
Except for Earth, all the planets in the Solar System have been named after Greek and Roman gods and goddesses. Many have kept their names for hundreds of years, while the planets discovered after the invention of the telescope were named due to this tradition. Mercury was named after the Roman god of travel, because he was swift, and the planet moves very quickly around the Sun. Venus was named after the goddess of beauty and love, because it shines very brightly, almost like a star in the s...
Time on other Planets
Time goes by differently on the other planets. However, let’s measure them based on the concept of time here on Earth: one day on Earth is 23.9 hours – this is the time it takes for the planet to rotate once on its axis, one year on Earth is around 365,25 days – this is the period it takes for our planet to complete one trip around the Sun. With this in mind, here is how the other planets move: 1. Mercury – 1 day =59 Earth days; 1 year = 88 Earth days 1. Mars – 1 day = 24.6 hours; 1 year = 68...

There are two main types of planets in the solar system. The four planets nearest the Sun—Mercury, Venus, Earth, and Mars—are called inner planets. They are rocky planets about the size of Earth or somewhat smaller. Jupiter, Saturn, Uranus, and Neptune are called gas giants.
