1 dzień temu · The nearest star to the Earth, apart from the Sun, is Proxima Centauri, 4.2465 light-years (40.175 trillion kilometres) away. Travelling at the orbital speed of the Space Shuttle, 8 kilometres per second (29,000 kilometres per hour), it would take about 150,000 years to arrive.
1 dzień temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth.
2 dni temu · Calculation of direction between two geographical points. To determine the direction from the starting point between two points on the earth, use the following formula: Δφ = ln ( tan ( lat B / 2 + π / 4 ) / tan ( lat A / 2 + π / 4) ) Δlon = abs ( lon A - lon B )
6 maj 2024 · The Moon is an average of 238,855 miles away from Earth, which is about 30 Earths away. You might be surprised. Often when we see drawings of the Earth and the Moon, they look really close together.
