What else can I help you with?
How do you determine how far away stars are from earth?
use a piggy bank and measure the distance from the piggy bank and a star
Do scientists measure a stars distance from earth in meters?
No, they are much too far away, and you would have a number too large to be usable.
What is a light year and why do scientist use it?
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
How far is venus away from the sun in grams?
Distance is a measure of length, grams is a measure of weight.
How do you measure the height of an object too far away to measure the distance to the object?
You can use trigonometry to measure the height of an object that is too far away to directly measure the distance to. By measuring the angle of elevation from your position to the top of the object and knowing your distance from the object, you can use trigonometric functions to calculate the height.
What is the effect of the distance of the stars on its magnitude?
Magnitude is brightness. As stars are further away they're dimmer. It may seem like a star that twice as far away would be half as bright but it doesn't work that way. Brightness falls off in proportion to the square of the distance away. A star that is twice as far away is one-fourth as bright.
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
Are stars far away or close to the solar system?
stars are pretty far away from the solar system
Parallax cant be used on a star if the star is too?
We can't use parallax to measure a stars distance from the Earth if the star is already too far away. The angles used in parallax measurment are already very small, and if the star is beyond a certain distance from us the angle becomes too small to measure, and no distance can be determined.To date the largest distance that can be measured using parallax, with the Hipparchos sattelite, is about 1 600 light years. This will be improved with the European Space Agencies Gaia mission in 2012 and 2013.
If a star's parallax is too small to measure does that mean that it is close or far from Earth?
If a star's parallax is too small to measure, it means that the star is far from Earth. Parallax measurements are used to determine the distance of nearby stars by observing their apparent shift in position as Earth orbits the Sun. Stars with large parallaxes are closer to Earth, while stars with small or undetectable parallaxes are further away.
Why is the light year used to measure the distance between the stars and us instead of kilometres?
it is so far that kilometers wont work
Why do the stars look small?
Because they are so far away. Same principle applies to any object as it recedes into the distance.
