Moons that display few craters presumably. They all pass straight over the equator of the globe. Uranus's five biggest moons. have the closest magnetic field axis.
<h3>Which 4 moons are known?</h3>
There are many fascinating moons around the globe, but the Galilean satellites—Io, Europa, Ganymede, and Callisto—the first four moons identified beyond Earth—hold the most scientific curiosity.
<h3>Can Earth have Two moons?</h3>
Moon and Earth
The basic explanation is that Earth only has one moon, that we name “the moon”. It is the biggest and brightest object in the night sky, and the only solar system body except Earth that humanity have visited in our space travel activities.

Answer:
37.34372 kg
Explanation:
m = Mass
= Change in temperature
1 denotes water
2 denotes copper
c = Heat capacity
Heat is given by
In this case the heat transfer will be equal
Mass of copper block is 37.34372 kg
Answer:
The time taken by the satellite to orbit earth at its surface, t = 1.66 hr
Explanation:
Given data,
The velocity of the satellite, v = 15000 miles/hr
The distance of travel, d = 24901 miles,
It is equal to the circumference of earth,
So the time taken by the satellite to orbit earth at its surface,
v = d/t
t = d/v
Substituting the given values in the above equation,
t = 24901 / 15000
= 1.66 hr
Hence, the time taken by the satellite to orbit earth at its surface, t = 1.66 hr
