Solar System Facts | Information, Size, History and Definition

The solar system consists of the Sun; the eight official planets, at least three "dwarf planets", more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.)

Interesting Facts about the Solar System

Our solar system is a good example to understand exoplanets: Exoplanets are very far away and look tiny even using the most powerful telescopes. Examining planets in our solar system such as Jupiter, that have miniature solar systems, so we can watch how super-Earths outside of our solar system possibly work. Beyond the solar system:

Ceres is about 1/13 the width of Earth. The closest dwarf planet to the Sun, and the only dwarf planet in the inner solar system, Ceres orbits the Sun from an average distance of 257 million miles (413 million kilometers) Ceres is about 2.8 times farther from the Sun than Earth.

solar system

The solar system is also known as a planetary system. Since the 1990s scientists have found many planetary systems beyond our solar system. In these systems, one or more planets orbit a star—just as the eight planets in our solar system orbit the Sun. These planets are called extrasolar planets.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

Top 10 Facts About Our Solar System

1. There are 8 solar system planets. The 8 planets of our solar system are divided into the inner planets Mercury, Venus, Earth, and Mars, and the outer planets Jupiter, Saturn, Uranus, and Neptune.The inner planets, so named because they orbit closest to the Sun, are solid balls of rock and metal, while the outer planets with orbits beyond the asteroid belt are

What is a Planet? | Planets – NASA Solar System Exploration

Researchers have found hundreds of extrasolar planets, or exoplanets, that reside outside our solar system; there may be billions of exoplanets in the Milky Way Galaxy alone, and some may be habitable (have conditions favorable to life). Whether our definitions of planet can be applied to these newly found objects remains to be seen.

The solar system encompasses planets, moons, asteroids, comets, and dwarf planets, that orbit around the Sun at its center. The solar system was created about 4.6 billion years ago in a collapsing cloud of gas and dust that eventually flattened into a rotating disk. The two main regions of the solar system are the inner and outer solar systems.

The most cratered planet of the solar system is Mercury. Some believe that Saturn and Jupiter came close once and thus provoked the Great Flood on Earth. Every 15 years, the rings of Saturn briefly disappear from view due to their angle. Saturn produces the eeriest radio emissions in the solar system.
