In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. 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.

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.

Pluto Facts

Discovered in 1930, Pluto was long considered our solar system''s ninth planet. But after the discovery of similar worlds deeper in the Kuiper Belt, Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union. According to the 2006 IAU Resolution, "a dwarf planet is an object in orbit around the Sun that is large

Our Solar System

Our solar system formed about 4.6 billion years ago. The four planets closest to the Sun — Mercury, Venus, Earth, and Mars — are called the terrestrial planets because they have solid, rocky surfaces. Two of the outer planets beyond the orbit of Mars — Jupiter and Saturn — are known as gas giants; the more distant

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

Jupiter Facts

Jupiter is a world of extremes. It''s the largest planet in our solar system – if it were a hollow shell, 1,000 Earths could fit inside. It''s also the oldest planet, forming from the dust and gases left over from the Sun''s formation 4.6 billion years ago.

The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year, is in the range of 220–250 million years. Since its formation, the
