Why does it take less fuel to launch a space shuttle from moon than from earth?
To launch a space shuttle (or anything) you have to overcome gravity. The gravitational attraction of the moon is tremendously less than that of the Earth. The moon is much smaller than the Earth.
Is the moon bigger or smaller than earth?
moon is smaller
Why are smaller rockets needed on the moon?
Smaller rockets are needed on the moon because the moon has lower gravity than Earth, meaning less force is required to launch a rocket into space. Using smaller rockets also reduces the cost and complexity of the mission.
Is the moon bigger or smaller then the earth?
The Earth is bigger than the Moon. Earth's diameter is about 12,742 kilometers, while the Moon's diameter is about 3,474 kilometers.
Is the moon the same size bigger or smaller than earth?
The Moon is smaller than the Earth
Why does the moon casts a smaller shadow on earth?
because the moon is much smaller than earth
Is volume on moon different from on earth?
Volume- as in how much space something occupies- does not change. Neither does mass. However, WEIGHT is much less on the moon.
Why is the earth smaller then the moon?
It isn't smaller - Earth is larger.
Why is a persons weight different on earth than on the moon?
The gravity is less on the Moon, because the Moon is smaller than earth; it has less mass, and therefore "sucks" less than the earth. Weight is gravity times mass, you have the same mass on Earth and on the Moon (and in space), but weigh less on the moon.
Why is the moon smaller than the sun?
As objects get smaller, the ratio of surface area (heat loss to space) to volume (heat retained) gets larger. It is easier for the Moon to lose heat to space. Next, the Moon has no atmosphere to act as a blanket to prevent heat loss to space. Finally, the Moon is formed of lighter materials than the Earth proper, perhaps lighter materials from Earth. This means Earth's core has more heavy elements, that appear to actually be radioactive, heating the Earth's core.
Is earth larger than mercury?
Mercury is almost the same size as the Moon. The Moon is smaller than Earth. Mercury is then smaller than Earth.
Is the moon bigger then planet earth?
The moon is much smaller, about 1/4 the diameter of Earth.
