Solar System

Option “D” is correct.
Along with Earth, Mars have atmospheres that were primarily formed as a result of volcanic gas emissions, although the evolution of these gases on each planet has been very different.

Option “C” is correct.
Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red.

Option “C” is correct.
Mars has four seasons, roughly twice as long as those on Earth, but with more variation given Mars’ eccentric orbit and the fact its orbital speed varies more as a result (fastest when at perihelion; slowest at aphelion).

Option “A” is correct.
The answer seems to be “it’s possible”. Many scientists consider Mars and Earth twins because of the similarities between the planets. But they aren’t entirely alike. Some challenges would need to be overcome before humans could start calling Mars home.

Option “D” is correct.
Mars Pathfinder was launched December 4, 1996 and landed on Mars’ Ares Vallis on July 4, 1997. It was designed as a technology demonstration of a new way to deliver an instrumented lander and the first-ever robotic rover to the surface of the red planet. Pathfinder not only accomplished this goal but also returned an unprecedented amount of data and outlived its primary design life.

Option “B” is correct.
“The most exciting thing about Mars is that, at some point in time, 3.5 billion years ago, it’s clear the climate on Mars was more similar to Earth’s and had liquid water on its surface,” Voytek said. Then solar wind and radiation stripped most of its atmosphere away. Many scientists consider Mars and Earth twins because of the similarities between the planets. and it might be favorable for life in future.

Option “D” is correct.
Mars has a daily cycle that is quite similar to Earth’s. Its solar day is 24 hours, 39 minutes, and 35 seconds long, and the sidereal day is 24 hours, 37 minutes, and 22 seconds long. As a result, a Martian day (referred to as “sol”) is roughly 40 minutes longer than an Earth day.

Option “B” is correct.
Deimos is the satellite of Mars’ two moons. Being only 9 by 7 by 6.8 miles in size (15 by 12 by 11 kilometers), Deimos whirls around Mars every 30 hours.

Option “B” is correct.
When you see Mars in the night sky, it definitely has a reddish tint to it. People have been noticing that for a long time: even the ancient Egyptians called Mars ‘The Red One.

Option “C” is correct.
Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.
