We can learn a lot from sending rovers to Mars Martian geologic history, for example! But there are plenty of complications to sending people to Mars that many don't think...
The Moon is indeed slowly getting further and further away from Earth But that's not the whole story The Moon's orbit is slightly oval, so its distance is constantly changing...
So, it's true that the sun's gravity is always pulling the Earth toward it However, the way that orbits work is that the planet-- in this case, Earth-- is constantly 'falling'...
"Is the earth very slowly getting larger and why PS I stand to win 20 quid off me mate if the answer is yes !!!!" I am not aware that this is happening and I can think of no...
The Sun has a radius 100 times that of the Earth which means that about 1,000,000 (1 million) Earths would fit into the Sun! By the way, take a look at the NASA Kids...
This question is still very much studied in astrophysics! The answer depends on how "close" you want your close encounter to be It is very unlikely that a passing star entered the...
The gravitational field of the Moon would be unaffected by the radial distribution of mass within the Moon if the lunar mass were spherically symmetric (ie, density of the moon...
Be a little careful the Moon does rotate If you stood on the Moon, the stars would rise and set, just like they do on Earth, except that a lunar day is a month long, the same...
Sun rays generally don't converge to a certain "point" per-se Instead, light rays are released from the Sun's spherical surface in all directions The intensity of light rays is...
