The orbits of the four inner planets (Mercury, Venus, Earth, Mars) are fully visible, drawn as teal concentric circles around the bright ball of the sun at the center.

The planets in solar do not have circular orbit around the Sun, including Earth which goes around in an elliptical orbit. A new research is now looking at what really caused this change in the ...

Astronomers have sent artificial satellites (satellites that are manmade) to orbit several Solar System objects, including Jupiter, the asteroid Vesta and Mars. Polar orbits take the satellites ...

When you first learned about the Solar System, you probably saw diagrams that made it look orderly, with planets arranged in circular orbits around the Sun on a flat disk. But in reality, our Solar ...

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...

But our own Solar System's disc is relatively warped, with the orbits of its planets slightly tilted and more oval than circular. What happened to it? It's possible a heavy object fell into the mix ...

The diagram shows a satellite orbiting ... small orbits travel faster than objects in large orbits. The graph shows how the orbital speed of a planet changes with its distance from the Sun.
