Question

The planets Mars and Venus do not have any moons. Which of the following explanations for this ?
(A) both Mars and Venus have small mean radii
(B) both Mars and Venus have small mass
(C) both Mars and Venus are closer to Sun
(D) both Mars and Venus do not have water on them to attract moons

Answer 1

Hint
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.

Complete step by step answer
Most likely because they are too close to the Sun. Any moon with too great a distance from these planets would be in an unstable orbit and be captured by the Sun. If they were too close to these planets they would be destroyed by tidal gravitational forces. Its dense, acidic atmosphere produces a runaway greenhouse effect that keeps the surface at around 865 degrees F year-round, which is hot enough to melt lead. Venus also has a smaller orbit than Earth, which makes its seasons shorter, and variations in temperature and conditions extremely slight.
Option (C) is correct option.

Note
There are 79 known moons of Jupiter. The most massive of the moons are the four Galilean moons, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun.
