Saturn is the sixth planet from the Sun in the Solar System

Saturn is the second largest planet in the Solar System, after Jupiter. Saturn is a gas giant.

The thing that makes Saturn different is its very large system of rings around it. These rings are made of ice with smaller amounts of rocks and dust. Saturn also has 62 known moons orbiting the planet. The largest moon is Titan which is the second-largest moon in the Solar System. Saturn’s distance to the sun is about 1,400,000,000 km (869,000,000 mi). It takes Saturn 29.6 years to revolve around the Sun.

Venus is the second planet from the sun

Venus is a terrestrial planet because it has a solid, rocky surface like other planets in the inner solar system. Astronomers have known Venus for thousands of years. Venus is the brightest thing in the night sky except for the Moon. It is sometimes called the morning star or the evening star as at some elongations it is easily seen just before the sun comes up in the morning and, at other elongations, just after the sun goes down in the evening. Venus comes closer to the Earth than any other planet does.

Venus is quite similar to earth in size and gravity. But Venus’ atmosphere (air) is mostly carbon dioxide with clouds of sulphuric acid which makes it very poisonous to humans.

The pressure on Venus’ surface is 92 times that of Earth. Venus has no moons. Venus spins very slowly on its axis and it spins in the opposite direction to the other planets. The ancient Romans named it after their goddess Venus.

Pluto is a dwarf planet in the Solar System

Pluto is the ninth-largest body that moves around the Sun. At first, Pluto was called a planet. Now, it is the largest body in the Kuiper belt.

Pluto is mainly made of rock and ice. It is quite small. It is about a fifth (⅕) of the weight of the Earth’s Moon. It is only a third (⅓) its volume. It has an odd orbit and this orbit is very sloped. It takes Pluto to 30 to 49 AU (4.4–7.4 billion km) from the Sun. This causes Pluto to sometimes go closer to the Sun than Neptune.
