A light year is a measure of distance not time. A light year is the distance light travels in one year.
So for light to travel 6,300 light years, would take 6,300 years
The Crab Nebula is within the Milky Way galaxy, but about 2000 parsecs away from Earth, or about 6300 light years. It is still expanding from the initial supernova (observed in 1054 AD) and is currently about 11 light-years in diameter.
6300
The surface temperature (of the main component of this binary star) is about 6300 degrees Celsius.
6,300 years
The COSMOS 2607238 galaxy (one of the galaxies in the COSMOS survey) is a barred spiral galaxy 6300 million light-years from Earth in the Sextans constellation, and is 100,000 light-years in diameter, and contains about 100 billion stars.

it is equal
3,150 + 3,150
Because we're rounding to the nearest hundred, the answer is either 6200 or 6300. Because 75 is greater than or equal to 50, we round up to 6300.

1 kilometers is equal to 1000 meters, so 6.3 km is equal to 6300 m. (:
The ACS-GC 13003331 galaxy (one of the galaxies in the Extended Groth Strip survey) is a spiral galaxy 7500 million light-years (redshift of 0.91) from Earth in the Bootes constellation, and is 120,000 light-years (1.2 times larger than the Milky Way) in diameter, and contains about 200 billion stars (200 percent of the Milky Way's stars). It emitted its light 7500 million years ago when the universe was 6300 million years old.
3% of 6300 = 3% * 6300 = 0.03 * 6300 = 189
Expressed as a surd in its simplest form, sqrt(6300) = 30 sqrt(7). Expressed as a decimal, rounded to two decimal places, this is equal to ±79.37.
