Why is the distance to planets usually given in kilometers whereas the distance to the stars are given in light years?
Because stars are much, much further away than planets are. What sounds better? The nearest star is 4.24 lightyears away or 40,132,658,900,000 (Or 4.013x10^13) kilometers? To go even deeper, it's better to give distance in astronomical units (1 au = Mean distance from Sun to Earth), megameters (1Mm = 1,000km) or gigameters (1Gm = 1,000,000km) when refering to planets. When refering to distance, it's best and least confusing to use smaller units. If you reference somoething extremely far away, you would often use parsecs (Be it parsecs, megaparsecs, etc.). where 1 parsec = 3.2 lightyears.
How many kilometers away is an object whos distance is 8 lightyears?
8 light years = 75685843780650 kilometers
What is the distance from earth to Denebola?
Denebola is located approximately 36.9 light-years away from Earth.
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
If a star has a parallax of 0.20 arc seconds what is the distance to that star?
I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.
What is the distance modulus for a star that is 1 million parsecs away?
A distance of one million parsecs (approximately 3,262,000 light-years) is commonly denoted by the megaparsec(Mpc).
What distance is rigel have?
Rigel is 260 +/-20 parsecs away.

What is the distance to the second nearest star from earth?
it is 4.24 lightyears away
How long is the distance from earth to the star Gemini?
over 9000 lightyears away
Calculate distance to Sirius in parsecs and ligh years?
Sirius is approximately 2.6 parsecs or 8.6 light years away from Earth.
What is Alpha Centauris approximate distance from Earth in parasecs?
Alpha Centauri is approximately 1.34 parsecs away from Earth. This distance makes it the closest star system to our Solar System. In light-years, this translates to about 4.37 light-years.
How far away is the moon in lightyears?
it is 0.0000000406 lightyears away, it is pretty close.
How many kilometers away is an object whos distance is 8 lightyears?
8 light years = 75685843780650 kilometers
A star has a parallax of 0.75 of arc How far away is this star in light years?
The distance to the star can be calculated using the parallax angle (in arcseconds) and the formula: distance (in parsecs) = 1 / parallax angle (in arcseconds). Given a parallax of 0.75 arcseconds, the star is approximately 1.33 parsecs away. Converting parsecs to light years (1 parsec ≈ 3.26 light years), the star is about 4.34 light years away.
What is the distance from earth to Denebola?
Denebola is located approximately 36.9 light-years away from Earth.
How far away are Cancer's stars?
The closest (DX Cnc) is 11.8 lightyears away. The farthest is nearly 4000 lightyears away.
