What else can I help you with?
When should you use light years?
Light years are used to measure distance from Earth to distant stars and planets.
The method astronomers use to measure the distance to stars that are less than 1000 light years from earth?
The method called "parallax.
How far is Deneb from the Earth?
The distance from Deneb to the earth is still somewhat uncertain. One 2008 study puts the most likely distance at 1,550 light-years, but there is still a considerable uncertainty of more than 10%. The reduced parallax uncertainties do not rule out a distance as close as 1,340 light-years or as far as 1,840 light-years. Deneb is the farthest first-magnitude star from Earth. (The number of years required for its light to reach earth is the same as its distance in light years.)
What are the stars the three stars on this hunters belt?
The three stars that compose the hunters belt in the constellation of Orion are: Alnitak, Alnilam and Mintaka. They are 800 light-years, 1340 light-years and 915 light-years away from us respectively (but, of course, from earths perspective they are in a neat line).
How many galaxies are in the Power Rangers Universe?
There are over 100 billion galaxies (with 100 billion+ stars (each containing 9 planets and 170+ moons)) in each one; as well as asteroids and nebulae) in the Power Rangers universe. Their light has taken 13 billion years to reach Earth.
Does it sometimes take millions of years for starlight to reach earth?
Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
How long does it take for light from big dipper stars to reach earth?
The stars from the Big Dipper are approximately 80 light years away from Earth, meaning it takes 80 years for the light from those stars to reach us. This means that the light we see today from the Big Dipper actually left those stars 80 years ago.
How long does it take stars light to get to us?
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
What takes longer to reach earth light from the sun or light from other stars?
Light from the sun because all light travels at the same speed, and the sun is the closest star to the earth, so therefore the light from the sun reaches the earth before light from other (further away) stars
Could you tell me about the stars?
our sun is much closer to us than the stars. Light from the sun takes about eight minutes to reach Earth, but the light fromthe next nearest star takes a sevral years to reach us
How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
How long does it take starlight to reach us?
The distance of Altair is listed as 16.8 light-years.That's something like 1.1 million times the distance from the earth to the sun !
Is the distance between stars and earth measured in kilometres or light-years?
Light Years.
Why are the stars that you see in the sky now how they looked like thousands of years ago?
The light from stars takes a long time to reach us due to their immense distance from Earth. When we observe a star in the sky now, we are seeing the light that was emitted by that star thousands of years ago. This is because the speed of light is finite and the universe is vast.
Do constellations have a fixed shape?
because stars cannot move fast enough for people to be able to tell that they moved from Earth, and also because it takes thousands of years for the light of stars to reach Earth. If the big bang happened at one particular moment, it would take eight minutes for the first light to reach earth (the sun is the closest star to the earth, and it is eight light minutes away)
Why do some stars look like dimle the sun feels very bright and big?
The sun is relativly close to the Earth compared to other stars. It takes light less than 9 minutes to get to us from the Sun, but it takes several years, to billions of years, for star light to reach Earth.
In distance in space between stars and earth measured in kilometres or light years?
in light years
