Jupiter protects the Earth by “eating up” any asteroid or comet that ventures near thanks to its gravitational pull, earning the nickname “vacuum cleaner of the solar system.”
There are “lone planets” that roam endlessly through space without ever going into orbit. They are actually predicted to be more common than stars.
We have a good idea of what other planets would smell like based on their atmospheric composition. Venus and Mars would smell like rotten eggs, while Uranus is odorless.
There exists a planet between Mars and Jupiter known as Ceres. It’s a dwarf planet, like Pluto, and may contain water and an atmosphere.
Astronomers have found a planet that rains liquid glass sideways amid 4,500 mph winds.
Billions of Jupiter-sized orphan planets, ejected from their orbits, roam the universe alone in the dark of space.
There is a mysterious dwarf planet between Mars and Jupiter called ‘Ceres’ which has never been visited by spacecraft or photographed in detail, however, Earth-bound telescopes reveal a large bright shining spot on the surface of this planet, the origin and nature of which are unknown.
Not only are there rogue planets floating through space completely alone, not orbiting any stars, but it’s possible that these pitch-black lonely planets support life.
The Mars One project is seeking to colonize Mars by 2023. The astronaut/colonists will spend the rest of their lives on the red planet.
Neptune was predicted to exist by mathematical calculations well before it was physically observed by telescopes.
