Mercury has a mass of 0.33x1024kg, and Earth has a mass of 5.97x1024kg. Thus, Mercury has a smaller mass than earth (or, in other words, Earth has a mass that's about 18x greater than that of Mercury).
If Mercury's volume was compared with Earth's volume, then 18 Mercurys could fit inside the Earth.
Neptune has a greater mass than Earth does.
earth is 1.88 times bigger than mars so i guess mars is 1.88 times smaller than earth Like so many other things, it depends what you mean. Diameter or volume? Or perhaps you are thinking of "mass". Anyway here's some data : Earth diameter: about 7926 miles Mars diameter : about 4222 miles That makes Earth about 1.88 times bigger, as the previous contributor wrote. But in terms of volume Earth is much bigger, because volume depends on the radius (half the diameter) cubed. So it's not surprising that the Earth's mass is much bigger too. The mass of Mars is only about 11% of the Earth's mass.

Jupiter has a mass 317.8 times greater than Earth. In terms of physical size, Jupiter has a volume 1321.3 times that of the Earth.
The sun is 1,000,000,000,000 times bigger than the earth.
Depends what measurement you want to compare. Diameter of the Earth is about 4 times as big, therefore its surface area is about 16 times as big and its volume 64 times as big; the Earth's mass is 81 times as much as the mass of the Moon.
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
The Moon is in fact much smaller than the Earth. The Earth is about 12750 kilometers (7930 miles) in diameter; the Moon is only 3470 kilometers (2160 miles). The Moon is also less dense than the Earth; consequently its mass is only 1/81 that of the Earth.
The Sun is a star, it is Much Bigger than the Earth. It's probably thousands of times bigger than the Earth. Planets orbit around the Sun. One of those solar flares that leap out from the Sun like a flame from a fire is much bigger than the Earth.
Saturn is a planet made out of mostly gas. As gas has little mass, it is less dense than Earth. Remember that density is proportional to its mass and surface area.
Mercury is much smaller than earth.
