Because of the discrepancy between Earth’s polar and equatorial diameter, astronomers and scientists often employ averages. This is what is known as its “mean diameter”, which in Earth’s case is the sum of its polar and equatorial diameters, which is then divided in half. From this, we...
SpaceX is also working on orbital refueling to extend the range. CEO Elon Musk has been talking about Mars missions since Starship was the BFR, but that's not the only use case. The first Starship launches will most likely focus on operations in Earth orbit and the Moon. One of the ...
Jan Hendrik Oort calculated that the centre is in the direction of the constellation of Sagittarius. The centre of the Galaxy is commonly referred to as Sagittarius A*. It is estimated at a distance of 26,000 Light Years from Earth. The Galaxy's centre is estimated at 25,000 light-years...
When the moon moves completely into the Earth's dark shadow cone (called the "umbra") we call that a total lunar eclipse. At the moon's average distance from Earth of 239,000 miles [383,000 km], the umbra measures roughly 5,800 miles [9,334 km] in diameter. The moon is about 2...
Sometimes called the Ashen Glow or the Old Moon in the New Moon's Arms, the phenomenon is visible within a day or two of new moon, when sunlight reflected off Earth and back toward the moon slightly brightens the unlit portion of the moon's Earth-facing hemisphere. A backyard telescope ...

making them incredibly dense. This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes neutron stars a great test subject to challenge predictions in Einstein's theories, suc...
