Why is light from stars and planets considered to be parallel light?
The Sun, planets and stars are extremely far away from us ; hence, the rays reaching us diverge only very slightly. This results in parallel light rays, for all practical purposes.
Why are stars brighter than planets?
They are a lot closer than the stars. The nearest star, Alpha Proxima is 4 light years away. The planets are at most a few light hours away. Although they don't emit light, several of them have cloudy or sandy surfaces, making them highly reflective of sunlight. Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
Why is Space black or dark?
the space between stars and planets has insufficient particles to reflect the light back to us.
Why do planets appear brighter than stars?
Because they're very close to the sun and thus reflect a lot of the sunlight. It also helps that they are very close to us in terms of the other stars in the sky.
Why do planets appear to move through the background of stars?
planets are much closer to us than the stars
Why do planets seem brighter than stars?
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
The planets appear to move through the background of stars because?
planets are much closer to us than the stars
How does the distance of planets compare to the distance of stars?
Stars are all over Hollywood, planets are above us in the sky.
How does the telescope help us today?
* The telescope helps us understand space and the stars and other planets.
Do planets give us light?
No
What is the evidence that planets are closer to earth than the stars?
The evidence that planets are closer to Earth than the stars is the brightness of the light that each star gives off in the sky. The ones that are farther away are dimmer than the ones closest to us. We can see the planets closest to us in the night sky (Mars, Venus, and sometimes Mercury) because they reflect the light of the sun back to us so that we can see them - however you need to know where to look in the night sky to find them.
Is light from stars and light from planets the same?
Planets don't produce their own light, it is only reflected light from the Sun. The light from the Sun is exactly the same type of light that comes from all other stars, it is stronger only because the Sun is closer to us. Brightness is measured in magnitudes, the bright stars are magnitudes 0 and 1 and there are even two stars with a negative magnitude. The dimmest stars visible in perfect conditions are 6th magnitude. The Sun's magnitude is -26.7. If the distance goes up 10 times, the brightness goes down 100 times, which is exactly 5 magnitudes.
