How Old Is The Solar System?

A giant cloud of dust and gas, known as the solar nebula, crumbled in on itself about 4.6 billion years ago, forming what would eventually become the solar system’s Sun and planets. 

Meteorites, or space rock fragments that have fallen to Earth have assisted scientists in determining the age of the solar system. Some of these small fragments have broken off of moons or planets and can provide valuable scientific data about the chemistry and history of their home body.

Which Are The Planets That Make Up The Solar System?

Here is a short description of every planet that consists of the solar system before we head on to the space knowledge questions. A little brush-up can help you get the answers right.

Mercury

Mercury is the planet closest to the Sun. It is also the smallest planet in the solar system, measuring only about 3,032 miles (4,879 kilometers) in diameter and having no moons of its own.

Venus

Venus, named after the Roman goddess of love, is the second planet from the Sun and the hottest planet in the solar system. Its atmosphere is a thick layer of mostly carbon dioxide gas that traps heat, allowing the planet’s surface temperatures to reach a blistering 880 F (471 C). Astronomers announced the discovery of phosphine in Venus’s atmosphere in 2020.

Earth

Earth, the third planet from the Sun, is the only planet in the Universe known to support life. The presence of liquid water determines its habitability. The Earth orbits in the so-called Goldilocks zone, which means it is at the optimal distance from the Sun for liquid water to exist; any closer, the water would evaporate into a gas, and any farther away, the water would freeze.

Mars

Mars is known as the Red Planet because of the iron-rich dust covering its surface and making it rusty. Because of this red hue, the ancient Romans named Mars after their god of war.

Jupiter 

Jupiter is the solar system’s largest planet. It is a gas giant composed primarily of helium and hydrogen, unlike the inner planets. The name is derived from the Roman gods’ king (also known as Zeus in the Greek pantheon).

According to NASA, Jupiter, the fifth planet from the Sun, is twice as large as all of the other planets in the solar system combined, but it also has the shortest day of any planet, taking 10 hours to rotate around its axis.

Saturn

Saturn, the sixth planet from the Sun, is the solar system’s second-largest planet. Saturn’s most notable feature is its prominent rings. Saturn, like Jupiter, is a gas giant made up of helium and hydrogen, and it is the least dense of the planets.

Uranus

Uranus, the seventh planet from the Sun, was discovered using a telescope in 1781 by British astronomer William Herschel. The ice giant is heavier in composition than its gas giant neighbors, consisting of water, methane, and ammonia ice.

Neptune

The eighth planet from the Sun, Neptune, was discovered in 1846. However, even before the planet’s discovery, scientists predicted its existence due to its effect on Uranus’ orbit.
