The planets in the solar system

The solar system's age is 4.571 billion years old and the location is in the Milky Way Galaxy. Other than the planets, it consists of dozens of moons, the stars, the sun, and everything bound to it by gravity. Including known dwarf planets such as Pluto, Ceres, Orcus, Haumea, Quaoar, Makemake, Gonggong, Eris and Sedna. And millions of asteroids, meteoroids and comets.

The most important planets and stars are as follows:

Earth

The planet earth is the third planet from the Sun, and the only place known of so far that's inhabited by living beings. While Earth is only the fifth largest planet in the solar system, it is the only world in the solar system with liquid water on the surface.

Radius: 6,371 km

Age: 4.543 billion years

Sun

The Sun is the star at the center of the Solar System. It is a perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. Without the sun, Earth will destruct!.

Moon

The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth.

Earth has one moon, and there are more than 200 moons in the solar system. Most of the major planets- all except Mercury and Venus have moons.

Distance to Earth: 384,400 km

Radius: 1,737.4 km

Stars

The Milky Way galaxy is just one of the billions of galaxies in the universe. Within it, there are at least 100 billion stars; and on average, each star has at least one planet orbiting it.

Saturn

Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth, but is over 95 times more massive.

Distance from Sun: 1.434 billion km

Orbital period: 29 years

Jupiter

Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined; while being slightly less than one-thousandth the mass of the Sun.

Distance from Sun: 778.5 million km

Orbital period: 12 years

Venus

Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus appears in Earth's sky never far from the Sun, either as morning star or evening star.

Distance from Sun: 108.2 million km

Mass: 4.867 × 10^24 kg (0.815 M⊕)

Uranus

Uranus is the seventh planet from the Sun. It is named after Greek sky deity Uranus, who in Greek mythology is the father of Cronus, a grandfather of Zeus and great-grandfather of Ares. Uranus has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.

Distance from Sun: 2.871 billion km

Orbital period: 84 years

Radius: 25,362 km

Surface area: 8.083 billion km²

Neptune

Neptune is the eighth planet from the Sun and the farthest known planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third most massive planet, and the densest giant planet. It is 17 times the mass of Earth, and slightly more massive than its near-twin Uranus.

Pluto

Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris. Pluto used yo be a planet in the solar system but has been banished because of it's tiny size.
