100 000 000 000 000km is equal to 1.57 lightyear. Rigel, which is the brightest star in Orion, is 777 lightyear away from earth. Is this was measured in km, it would be 7 381 500 000 000 000 km away. It only makes it easier to express the to measure the extreme distances found in space. One would not measure the distance between New York and Paris in millimeters. The final number would have far too many digits.
What else can I help you with?
What do astromoners measure distance in between stars with?
light years
Do you use meters to measure the distance between stars?
Yes, astronomers use light-years to measure the distance between stars in space. A light-year is the distance that light travels in one year, which is about 9.46 trillion kilometers or 5.88 trillion miles. This unit of measurement is more practical given the vast distances in space.
Light years are used to measure distance between stars because?
. . they are a convenient unit. Another convenient unit is the parsec.
Which distance would a light -year be most appropriate for measuring?
A light-year is most appropriate for measuring astronomical distances between stars and galaxies due to its vast scale. It represents the distance that light travels in one year, which is about 5.88 trillion miles.
What is the units used to measure the distance of stars to the earth?
light years
What is the distance between star?
The distance between stars can be anything from light minutes to billions of light years.
Are the stars measured in light years?
Stars are not measured in light years. The distance between them is.
What units are for distance between stars?
The correct unit to describe the distance between stars is the "light year", the distance a photon of light would travel (through a vacuum) in a year.
What is the distance between (-3,6),(-3,-2)?
The distance between stars can be anything from light minutes to billions of light years.
What do astromoners measure distance in between stars with?
light years
Is the distance between stars and earth measured in kilometres or light-years?
Light Years.
What unit of distance would you use to measure the distance between two stars?
Light Years.
In distance in space between stars and earth measured in kilometres or light years?
in light years
Why is using a light year useful for measuring stars?
Because the distance between stars is so great.
What is used to measure distance between stars?
Light year or astronomical units
What do stars vary in?
expressed light. (light given off.)
How does the distance between planets compare to the distance of stars?
The distance between stars is a couple of order of magnitudes higher than the distance between planets.To put this into perspective, the distance between earth and the sun is 8 light-minutes and the distance between other planets doesn't go further than a few light-hours. On the other hand, the distance between our sun and the nearest star (alpha centauri) is 4.4 light-years. This means that this distance is about 38544 larger than the distance between planets.Beyond that, the distance between stars can be extremely high: a star on the other side of our galaxy will be about 100000 light-years away from us. The distance will keep rising as we move on to different galaxies, then different galaxy clusters, the super clusters and then, finally, the width of the universe.
