Solar System
What is a solar system? A solar system is essentially a star orbited by one or more planets bound to it by its gravitational pull. Our solar system is home to eight planets, several dwarf planets, over 200 moons, countless asteroids, comets, meteors, and other forms of planetary debris. For most of history, it was believed that our solar system

18.1: Introduction to the Solar System
The solar system is the Sun and all the objects that are bound to the Sun by gravity. The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Ceres, Makemake, Pluto and Eris are dwarf planets.

It is the coldest planet of the Solar System with temperatures at around -224 degrees Celsius. Uranus is the only planet that rotates on its side. Like Venus, it also rotates in the opposite direction. This planet has a long orbital duration, 84 years. A day on Uranus, on the other hand, is the shortest, lasting only 17 hours.

Our Sun: Facts
Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this speed, it takes about 230 million years for the Sun to make one complete trip around the Milky Way. The Sun rotates on its axis as it revolves around the galaxy. Its spin has a tilt of 7.25 degrees with respect to the

In the outer solar system, turbulent storms dot the atmospheres of the giant planets — Jupiter, Saturn, Uranus, and Neptune — allowing Hubble to become an expert storm tracker. For instance, Hubble has observed the downsizing of Jupiter''s most famous feature, the spinning, cyclone-like storm known as the Great Red Spot.

What Is the Solar System?
The solar system is located in one of the spiral arms of the Milky Way galaxy. It was born about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed. Most of the material was pulled toward a central point: nearly all of the solar system''s mass—99.8%—is in the Sun.

Solar System
The extent of the Solar System is defined by the solar wind — particles driven by the Sun''s magnetic field — and gravitational influence. The heliopause is the boundary created when solar wind particles collide with interstellar gas as the Solar System moves through the galaxy. The gravitational edge is much farther and is defined by the

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 inner planets orbit relatively close to the Sun and have solid surfaces. The outer solar system is where the gas giants
