What are Centaurs in astronomy?
A centaur, in planetary astronomy, is a small Solar System body with either a perihelion or a semi-major axis between those of the outer planets.
Does our solar system have an asteroid belt?
Meet the asteroid belt, a place in our solar system where small bodies – mostly rocky and some metallic – orbit the sun. These little worlds are also sometimes called minor planets. They move mostly between the orbits of the fourth planet Mars and fifth planet Jupiter.

Can humans live on Titan?
Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
Is there a planet called Titan?
Saturn’s largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.

Why is Europa red?
The startling colour is due to contaminating minerals rising from beneath the icy crust, possibly salts from the underground ocean. The regions of mottled red are chaotic terrain, parts of the moon’s surface with disrupted icy material that has been broken and shifted around.
What is red on Europa?
Despite their unnerving appearance, the red scars criss-crossing Europa are, of course, not biological. They are actually cracks and ridges marking weak lines within the moon’s ice crust, emphasised and exacerbated by the swelling and falling of tides due to Jupiter’s gravitational pull.
Is there an ocean on Europa?
Like our planet, Europa is thought to have an iron core, a rocky mantle and an ocean of salty water. Unlike Earth, however, Europa’s ocean lies below a shell of ice probably 10 to 15 miles (15 to 25 kilometers) thick and has an estimated depth of 40 to 100 miles (60 to 150 kilometers).
What are the reddish brown lines seen in Europa?
Jupiter Moon Europa’s Dark Lines May Be Salt from Underground Sea. The reddish-brown lines that crisscross the icy surface of Jupiter’s moon Europa may be radiation-bombarded sea salt from an underground ocean, a new study suggests.
