Is each martian moon smaller than earth's moon?
Yes, the martian moons are each smaller. Combined, they are smaller than Earth's moon. Phobos and Deimos are captured asteroids with diameters of 22.2 and 12.6 km respectively. Earth's satellite, the largest in the Solar System is 1738 km in diameter.
What is the size of Deimos moon?
15 × 12.2 × 10.4 km
What is the size comparison of Mercury and the Moon?
Mercury is only a half larger than the moon, with 1.45 times the surface area of our moon. Mercury-4,880 km Moon-3,476 km
Are moons big?
Some are bigger than others. The Earth's Moon is the largest compared to its mother planet, but the dwarf planet Pluto has the moon Charon which is apparently about half its size.The Earth's Moon is about one eightieth (1/81) the mass of the Earth, with a diameter of 3476 kilometers (2160 miles). The irregular Martian moon Deimos is only 10 km in diameter at its narrowest The smallest moons of Jupiter and Saturn are even smaller, down to about 0.3 km, where the line between moonand moonlet becomes vague.
Is the earth larger than the moon?
yes the moon is only about one-fourth the size of earth
What planet is the closest in size to the Moon?
Mercury. The average radius of the Moon is about 1700 km, which is about three-quarters the average radius of Mercury (around 2300 km).
Is a martian moon smaller than earth?
Yes, much smaller. Earth is much larger than even the largest moons in the solar system. The moons of Mars are tiny as far as moons go. Phobos has a mean diameter of 22 km (13.6 miles) while Deimos has a mean diameter of 12 km (7.5 miles). So the Martian moons are smaller than some cities.
What is the radius of atlas?
Saturn's moon, Atlas, has a radius of about 15 km. ("Atlas" has several other meanings, too.)
What is Mars' smallest moon?
Deimos is the smallest moon of Mars with a diameter of only 12.6 km
What planet has one moon?
Moons in the solar system besides "ours"(with estimated diameter (2xRadius)):Comment: Here I´m considering as "Moon" only those satelites that are large enough to be spherical, which leaves out for example, Phobos and Deimos (orbiting mars), and numerous other satelites of Jupiter, Saturn, Uranus and NeptuneJupiter : the galilean Moons:Io (~3650 km),Europa (~3100 km),Ganymede (~5200 km) &Callisto(~4800 km)Saturn:Enceladus (500 km),Tethys (1050 km),Dione (1100 km),Rhea (1500 km),Titan (5100 km),Lapetus(1400 km)Uranus:Miranda (470 km),Ariel (1160 km),Umbriel (1170 km),Titania (1550 km),Oberon (1520 km)Neptune:Triton (2700)
How many km is it from the earth to the moon?
Because the Moon's orbit is elliptical, its distance from Earth ranges from 356400 km to 406700 km, with an average orbital radius of 384401 km.
What planet is the size of earth's moon?
The only planet close in size to the moon is Mercury, the closest planet to the sun. The mean radius of the moon is 1737.10 km The mean radius of Mercury is 2439.7 km There are many dwarf planets that are close in size to the moon, but that would be another question.
