The answer will not even consider planets outside the solar system.
Also, some planets are more "squashed" than others and these are comparisons of their equatorial diamenters.
Mercury: 0.382 m
Venus: 0.949 m
Mars: 0.532 m
Jupiter: 11.209 m
Saturn: 9.449 m
Uranus: 4.007 m
Nepture: 3.883 m
Pluto: 0.19 m
What do you mean by "height" if you are not referring to the diameter? The diameter is the distance from one side of the circle to another, crossing its center. Due to the definition of what is a circle, all diameters have the same length, whether it be from left to right, from top to bottom, or at any other angle.
The only chords that are diameters are the chords that go through the center of the circle. All of the other chords are shorter.
Mercury, has 24 hours in a day, the same as the earth and all the other planets in the Universe.
If you weighed 100 lbs on Earth you would weigh 112.5 lbs on Neptune.See related for how much you would weigh on other planets.
It is the other way around. The radius is half the diameter.
Mercury has a diameter of about 4880 kilometers. In comparison, Venus has a diameter of about 12100 kilometers and Earth has a diameter of about 12750 kilometers. Mars has a diameter of only about 6800 kilometers, but all the other planets are much bigger than the Earth.
Based on classification by size, Uranus is one of the giant planets or gas giants. The other three giants planets are Jupiter, Saturn and Neptune. These gas giants all have diameters greater than 48000 kilometers. The other planets four planets are called the small planets. The small planets all have diameters less than 13000 kilometers.
The diameter of Mercury is: 4879.4 km (3032 miles). This is 0.3829 Earth diameters.*Because of its extremely slow rotation, Mercury has no appreciable equatorial bulge as found on other planets.3,032.3 miles.
Earth is a little bigger than the other terrestrial planets (Mercury, Venus, and Mars), but the immensity of the jovian planets (Jupiter, Saturn, Uranus, and Neptune) cannot be matched by Earth's. Jupiter, the largest planet, has a diameter over eleven times greater than that of Earth.
Venus, a terrestrial planet, is small compared to the gas giants within our solar system. It's diameter is equal to 12,104km, which is larger than the diameter of Mercury and Mars, but smaller than all other planets (including Earth, which has a diameter of 12,756km).
If you have an 18 inch diameter sphere on top, you'll have a 36 inch diameter sphere in the middle and a 54 inch diameter sphere on the bottom. 18 x 2 = 36 and 18 x 3 = 54
Earth and Moon to Scale. 1 pixel = 600 kilometers. The average distance between Earth and Moon is approximately 30 times Earth's diameter. moon is also much much smaller than many other planets.
The volume of Pluto is 7.5 x 109 km3 or 0.0066 Earths... it would take 151.5 Pluto's to make up the volume of the Earth. Also, the diameter of the earth is 12,756 km and pluto's diameter is 2,296 km, meaning that it would take 5.55 plutos to equal the diameter of the earth.
Mercury is the smallest planet in our solar system, a little under two fifths of Earth's diameter.
It varies. It is stronger on some planets and weaker on others. The strength of gravity on any planet depends on its mass and diameter.
Earth's moon is very large in proportion to its planet. It is just over one quarter of Earth's diameter. While several moons in the solar system are larger than our moon, they orbit much larger planets.
Earth is about 7926 miles in diameter. Venus is about 7,520 miles and diameter. Earth is only 5.4% wider in diameter than Venus. They are very close in size, that being the reason it is sometimes called Earth's sister planet or twin. Other than size, the two planets are not very similar.
