Detailed explanation-1: -The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.
Detailed explanation-2: -Only 40 percent larger in diameter than the Moon, Mercury is the closest planet to the Sun, and its sunlit surface is hot enough to melt lead. The planet is so small and so far away from Earth that it was only a dull white blur in telescopes before the Space Age.
Detailed explanation-3: -Earth is nearly 13, 000 kilometers across. The smallest terrestrial planet, Mercury, has a diameter about 40 percent of that size. Jupiter, the biggest planet, is more than ten times larger than Earth.
Detailed explanation-4: -Largest Planet: Jupiter Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140, 000 km, is about 11 times Earth’s diameter. (Jupiter’s Great Red Spot, even at its current diminished size, spans 15, 900, just over a full Earth diameter.)
Detailed explanation-5: -2) How big is the Moon? This one’s another easy approximation to remember: The Moon is about one-fourth (or a quarter) the size of Earth in width. Put another way, Earth is about four times wider than the Moon. That’s just about as wide as the United States or Europe.
