Oct 11, 2024 · For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
Oct 21, 2021 · Regarding a year, there are multiple ways to define the concept from an astronomical point of view. Two obvious approaches based on the Earth's orbit about the Sun are the time it takes for the Earth to revolve by 360° degrees with respect to the stars.
A light-year, alternatively spelled light year (ly or lyr [3]), is a unit of length used to express astronomical distances and is equal to exactly 9 460 730 472 580.8 km, which is approximately 5.88 trillion mi.

One common misconception about the light year is thinking it is a unit of time. This arises because the unit has the word “year” in it. The length of a light year is a length or distance, not a time (9.46 x 1012 kilometers or 5.88 x 1012miles).
The light year is defined with the speed of lightdefined as 299792458 m/s and the year being a Julian year (365.25 days). There are different ways to measure the length of a year on Earth. The light year is defined as distance light travels in a Julian year (365.25 days). This is slightly different from the Gregorian year (365.2425 days). The Grego...
In addition to the light year, two other units of length are used in astronomy: The astronomical unit (AU or au) is the distance from the Sun to the Earth. The distance between the Sun and Earth changes throughout the year because Earth’s orbit is an ellipse, but is equal to approximately 93 million miles or 150 million kilometers. In 2012, the AU ...

This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
Aug 28, 2023 · To measure really long distances and how fast light travels, astronomers and other scientists use a unit called a light-year. To reach the previously mentioned Proxima Centauri, it'd take 4.25 years at light speed.
A year is the length of time that it takes for a planet, satellite, or other celestial body to complete one orbit around the Sun (or in the case of extrasolar planets, around their star). For comparison, the orbital period of the Moon around the Earth is related to the month.
