Explanation:
Explanation number7- Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus.
Explanation number8- all planets revolve around the sun
Explanation number9- And unlike any other planet, Uranus rotates on its side
Explanation number10- Titania orbits at a mean distance of 435,840 km (270,820 miles) from the centre of Uranus, which makes it the second outermost of the planet's major moons. Its orbital period is 8.706 days, as is its rotational period.
