Our Solar System

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. Planets, asteroids, and comets orbit our Sun. They travel around our Sun in a flattened circle called an ellipse. It takes the Earth one year to go around the Sun. Mercury

NASA Telescope Reveals Largest Batch of Earth-Size, Habitable

Scientists using the Spitzer Space Telescope and ground-based telescopes have discovered that there are seven Earth-size planets in the system.

How many exoplanets are there?

To date, more than 5,000 exoplanets have been discovered and are considered "confirmed" out of the billions in our galaxy alone. There are thousands of other "candidate" exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real. Remarkably, the first exoplanets were just discovered in the []

In Depth: Exoplanets
