What does our Solar System really look like? If we were to somehow fly ourselves above the plane where the Sun and the planets are, what would we see in the center of the Solar System? The answer took a while for astronomers to figure out, leading to a debate between what is known as … Continue read…

Our solar system is planetary system that orbits a star and all of the objects that travel around it-eight planets, dozens of moons and millions of asteroids, comets and meteoroids.

Most stars host their own planets, so there are likely tens of billions of other solar systems in the Milky Way galaxy alone. We've discovered thousands of planetary systems around other stars.

The planetary system we call home is located in an outer spiral arm of the vast Milky Way galaxy. It consists of the Sun (our star) and everything that orbits around it. This includes the eight planets and their natural satellites (such as our moon), dwarf planets and their satellites, as well as asteroids, comets and countless particles of smaller debris.

10 Things to Know About Our Solar System

What Spacecraft are Headed into Interstellar Space?

Five spacecraft have achieved enough velocity to eventually travel beyond the boundaries of our solar system. T wo of them reached the unexplored space between the stars after several decades in space.

Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. Both spacecraft are still in communication with Earth. Both spacecraft launched in 1977.

NASA's New Horizons spacecraft -currently exploring the an icy region beyond Neptune called the Kuiper Belt-eventually will leave our solar system.

Pioneer 10 and Pioneer 11 also will ultimately travel silently among the stars. The spacecraft used up their power supplies decades ago.
