Anyone know which planet is closest to Earth in size?

Question

Is it Mercury, Venus, Mars, or Saturn?

Answer 1

It is Venus.

Mercury and Callisto are even closer in size to one another than Venus and Earth are to one another. And Ganymede and Titan are pretty similar in size too.

Here is a table of the radii of the 18 largest objects in our solar system,

by radius in kilometres and size relative to Earth:

1 Sun 696,000 109.25
2 Jupiter 69,911 10.97
3 Saturn 58,232 9.14
4 Uranus 25,362 3.98
5 Neptune 24,622 3.87
6 Earth 6371.0 1
7 Venus 6051.8 95.0%
8 Mars 3390.0 53.2%
9 Ganymede 2631.2 41.3%
10 Titan 2575 40.4%
11 Mercury 2439.7 38.3%
12 Callisto 2410.3 37.8%
13 Io 1821.5 28.6%
14 Moon 1737.1 27.3%
15 Europa 1561 24.5%
16 Triton 1353.4 21.2%
17 2003 UB313 1200 ± 50 19%
18 Pluto 1153 18.1%

Ganymede, Callisto, Io and Europa are the 4 largest moons of Jupiter (discovered by Galileo Galilei on January 7, 1610), Titan is the largest moon of Saturn (discovered by Christiaan Huygens on March 25, 1655) and Triton is the largest moon of Neptune (discovered by William Lassell on October 10, 1846).

Mercury is smaller than 2 moons, Pluto smaller than 7 moons,

Answer 2

Venus

Venus

Answer 5

VENUS


Earth seems to us like a pretty big place. Well, Jupiter has 317 times more mass than Earth! Saturn is 95 times as massive as Earth. But even with those giants hogging all that mass, the Sun contains 99.86% of the mass of the entire solar system!

It's a wonder there's any matter at all left over for us!

The picture below gives a better idea of how the sizes of the Sun and the planets compare with each other. If Earth were about 2 millimeters across, as it is in this picture, the Sun would be almost 218 millimeters (about 8-1/2 inches) across!

The picture below shows how the sizes of the moons of the different planets compare with each other and with the size of Earth.

Answer 6

Venus. The size difference between Earth and Venus is only about 100 miles (Earth being the larger of the two).

Answer 7

Definitely Venus, it's about 95 percent the size of earth while mars is only about 53 percent the size of earth. Mercury is much, much smaller, and Saturn is much, larger

Answer 8

Venus.

Answer 9

Venus.

Answer 10

It's Venus.
