How many light years away is hadar from earth?
The figure isn't unanimously agreed. In a quick web search, we found estimates ranging between 315 and 525 light years.
You measure the distance between stars in light years A light years is the distance that light travels in one years about 6 trillions miles?
Good rounding! The exact number of miles of a light-year is 5,865,696,000,000 miles. The farthest scientists have ever seen is about 13.5 trillion light-years. To figure out how many miles that is you would multiply the 2 numbers together. Cool huh?
How many years equals 42 light years?
None. "Year" is a period of time, but "light year" is a distance ... the distance light travels in a year. If a distance could be converted to a time, then you'd be able to figure out how many minutes wide your bedroom is.
How far away is the moon from earth in light years?
The moon is about 1.278 light-seconds from Earth.Converting that figure to the equivalent fraction of a year, I get0.000 000 040 486 light-year (rounded)
How do you figure out how many sec min hrs it takes for a radio wave to reach a star that is 5 light years away?
The answer is right there in the words of the question. Radio and light are the same physical phenomenon, and they travel at the same speed. The star is 5 light years away. That means the distance that light ... and radio ... travel in five years. It takes light from the star 5 years to reach us, and it takes radio from us 5 years to reach the star.
How thick is your galaxy?
The thickness of the Milky Way is still a matter of debate amongst scientists, and even in part still open to definition; the figure of 1,000 light years is often quoted; but recent studies tend to indicate a higher figure. One particularly extensive study aimed at finding the answer to this question led by Bryan Gaensler in 2008 puts the figure at between 6,000 and 12,000 light years, if you include stars and gas.
How do you shine a light for the world?
figure it out
What is the diameter of the Shapley supercluster?
Super clusters do not have defined boundaries, not a defined shape. A ballpark figure would put the diameter at about 100 million light years, but extending to about 250 million light years at the extreme. See related link for a pictorial of the cluster
What is the distance of the Orion nebula to the milky way?
Both of those galaxies are extended objects in themselves, with dimensions ofthousands of light years across each one, so no single figure can be precise.The round figure that's often used is . . . . . 2.5 million light years.
How do you use light to observe the universe?
you figure it out
Is a beam a light from a flash light a geometric figure?
yes, a straight line
What is an arcminute?
An astronomical archminute consists of 2000 light years. One can define the size of a galaxy by light years or archminutes. the closest spiral galaxy to our own is known as the M31 galaxy in the constillation Andromeda (all facts can be backed up, just search M31 and Andromeda on simple google search to confirm).The M31 galaxy is 200,000 light years wide and 100,000 light years high. also known as 100 archminutes by 50 archminutes. of coarse all of these measurements go back to the simple base figure of the speed of light.1 light year = distance light travels in a year1 archminute = distance light travels in 2000 years
