basic solar system

Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium.

Our solar system is made up of a star, eight planets, and countless smaller bodies such as dwarf planets, asteroids, and comets. Our solar system orbits the center of the Milky Way galaxy at about 515,000 mph (828,000 kph). We''re in one of the galaxy''s four spiral arms.

Our solar system is made up of the sun and all the amazing objects that travel around it. Learn more about the planets, asteroids, and comets in our solar system. Skip to content

Sun 101. Earth Science, Astronomy. The sun keeps the planets in its orbit with a tremendous gravitational force. What would happen if it disappeared entirely? Learn about the star at the center of our solar system, and how it is critical to all life as we know it. Grades. 5 - 12. video. Mercury 101. Earth Science, Astronomy.

Revolving around the sun are eight planets. The planets are divided into two categories based on their composition, terrestrial and Jovian. Terrestrial planets, including Mercury, Venus, Earth, and Mars are primarily made of rocky material. Their surfaces are solid. They don''t have ring systems.

The solar system has one star, eight planets, five dwarf planets, at least 290 moons, more than 1.3 million asteroids, and about 3,900 comets.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.

The solar system consists of the Sun, planets, dwarf planets, moons, and numerous smaller objects such as comets and asteroids. 194 moons, 3,583 comets and 796,289 asteroids have been found in the solar system. 99.86% of the solar system''s mass is found in the Sun. The majority of the remaining 0.14% is contained within the eight planets.

Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

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.
