The Milky Way is the galaxy that contains our solar system. This name derives from its appearance as a dim “milky” glowing band arching across the night sky, in which the naked eye cannot distinguish individual stars. Observational evidence for the Milky Way being made up of distant stars first came when Galileo pointed his telescope towards the Milky Way, observing a large amount of faint stars.

Correct Option: A

Mercury is closer to the sun, but the atmosphere on Venus actually makes it hotter. Even on the night side, the temperature doesn’t drop by much (comparatively) because of the carbon dioxide, about 95%, atmosphere. The atmospheric pressure of Venus is also about 90 times greater than that of Earth.

Jupiter is the fifth planet from the Sun and is the largest planet in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains two and a half times the mass of all the other planets combined. It has a mass of 1.9 × 1027 kg and is 142,800 kilometers (88,736 miles) across the equator.
