Solar System Universe Galaxy Order
Our planetary arrangement is located in an outer spiral arm of the Galaxy galaxy.
The Latest
Our solar system consists of our star, the Sun, and everything bound to information technology past gravity – the planets Mercury, Venus, World, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such equally Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. Across our own solar system, nosotros have discovered thousands of planetary systems orbiting other stars in the Milky Mode.

FAQ: Which Spacecraft are Headed to Interstellar Space?
Five spacecraft take achieved enough velocity to eventually travel beyond the boundaries of our solar organisation. Ii of them reached the unexplored space betwixt the stars after several decades in space.
- Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. Both spacecraft are withal in communication with World. Both spacecraft launched in 1977.
- NASA's New Horizons spacecraft is currently exploring an icy region beyond Neptune chosen the Kuiper Chugalug. It somewhen volition leave our solar system.
