If Earth is not ejected during a stellar encounter, then its orbit will decay via gravitational radiation until it collides with the Sun in 10 20 (100 quintillion) years. [110] If proton decay can occur and Earth is ejected to intergalactic space, then it will last around 10 38 (100 undecillion) years before evaporating into radiation. [111]
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years . [ 2 ]

All good things must come to an end, and, unfortunately for us, that includes the sun. But just how much time do we have until the light goes out? All good things must come to an end, and ...
In approximately 300,000 years, WR 104, a triple star, is expected to explode in a supernova. It has been suggested that it may produce a gamma ray burst that could pose a threat to life on Earth should its poles be aligned 12° or lower towards Earth. However spectroscopic observations now strongly suggest that it is tilted at an angle of 30 ...
The moon will appear to move in front of the sun beginning at 2:07 p.m. on April 8 in Rochester, New York. The window of totality is just 3 minutes and 38 seconds, with variance for location, and ...
They will continue to orbit their star, their speed slowed due to their increased distance from the Sun and the Sun's reduced gravity. Two billion years later, when the Sun has cooled to the 6,000–8,000 K (5,730–7,730 °C; 10,340–13,940 °F) range, the carbon and oxygen in the Sun's core will freeze, with over 90% of its remaining mass ...
