How many planets are in our Solar System?
Our solar system includes the Sun, eight planets, five officially named dwarf planets, hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms.
How did the Solar System form?
The mass at its centre collected to form the Sun and a flat disk of dust around it. This eventually formed the planets and other bodies of the solar system. The solar system consists of the Sun, planets, dwarf planets, moons, and numerous smaller objects such as comets and asteroids.
How big is the Sun compared to Earth?
The Sun is about 100 times wider than Earth and about 10 times wider than Jupiter, the biggest planet. The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.
What percentage of the Solar System is found in the Sun?
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. The four smaller inner planets, also known as the “terrestrial planets”, are primarily composed of rock and metal.
How fast does our Solar System orbit?
Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). It takes about 230 million years to complete one orbit around the galactic center. An artist's concept of our solar system. Learn about the inner planets, the outer planets, and the dwarf planets.
What is the largest object in the Solar System?
The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it.
