Names and order of planets in the solar system

You must have learned about the solar system by sitting in primary school. From the names of the planets to their order.

The Solar System consists of the Sun, four inner planets and four outer planets. The planets revolve around the Sun.

The 4 Inner Planets and Their Order in the Solar System

1. Mercury

The planet first and closest to the Sun has a very hot temperature. The surface temperature of Mercury reaches 430 °C during the day.

The temperature drops to -200 °C at night. However, it is not the hottest planet.

2. Venus

Venus is very close to the Sun because it is not far away from Mercury. The day temperature reaches up to 471 °C.

Venus is said to be the hottest planet in the solar system. Not only this, the planet is also called the morning star which has the brightest rays.

3. Earth

Earth is called the planet of life, as it is mostly filled with nitrogen and oxygen. This blue planet has a natural satellite called the Moon.

4. Mars

Mars is nicknamed the Red Planet. Because, there is a lot of sand dust on the planet which makes it red in colour.

With temperatures reaching 60 °C, Mars has a very large mountain called Olympus Mons.

The atmosphere is relatively dusty and contains particles up to 1.5 m in diameter that give it a brownish-yellow appearance. Mars is the planet whose seasons are similar to Earth’s.

4 Outer planets and their order in the solar system

1. Jupiter

The planet has many satellites, formed from a mass of gas in the form of helium and hydrogen. Jupiter is the name of the largest planet in the solar system. The diameter of the planet at the equator is 142,984 km (88,846 mi). The mass of Jupiter is 2.5 times the mass of all the planets in the Solar System.

2. Saturn

Next in order is the planet Saturn which is famous for its rings. The ring extends from 6,630 km to 120,700 km (4,120 to 75,000 mi) above the equator.

The ring is dominated by water ice and small amounts of tholin compounds, and the layer is showered with about 7 percent of the abstract carbon. Saturn is the second largest planet in the solar system.

3. Uranus

Uranus has the third largest radius, as well as the fourth largest mass in the Solar System. This planet was first discovered using a telescope.

The methane gas content makes Uranus blue-green. The atmosphere of Uranus is the coldest planetary atmosphere in the Solar System. Uranus is composed mostly of ice and rock.

4. Neptune

Neptune is the last and coldest planet in the solar system. The temperature of the planet is -200 °C.

This planet is as old as the Sun, which is 4.6 billion years old. Like Earth, Neptune is blue because its atmosphere is made up of helium and hydrogen.

There are only 8 planets in the solar system. Pluto is not included because it is considered ineligible as a planet.
