Why do the difference between two stars does not appear to change?
Does the question mean the distance between two stars? It does change, but very slowly on a human time scale. In 100,000 years most of the familiar constellations will look quite different.
Why do stars appear one by one?
Stars appear one by one as we look into the night sky because of the vast distances between them. Each star is at a different distance from us, so we see them as individual points of light. Additionally, the Earth's rotation causes stars to rise and set at different times, further contributing to stars appearing one by one.
Why do billions of stars appear as big patches of light in the night sky?
Billions of stars appear as big patches of light in the night sky due to their distance from Earth. From our perspective, the light from individual stars merges together to create these patches, known as galaxies or star clusters. These collections of stars appear as cohesive shapes due to their sheer number and the vast distances between them and us.
What do astromoners measure distance in between stars with?
light years
What is a stellar unit?
A stellar unit refers to a unit of distance used in astronomy to measure the distance between stars. It is typically equivalent to the mean distance between stars within a galaxy, which can vary depending on the galaxy being observed.

Why do distant stars that are actually very far from each other appear to be closed together in the sky?
because its for from stars
Why do some stars change elevation more than others?
Stars appear to change elevation due to the rotation of the Earth, causing different stars to move in and out of view. Stars near the celestial pole change elevation less as the Earth rotates, while stars closer to the celestial equator change elevation more as they cross the sky from east to west.
What is a cosmic distance?
A distance in space, between stars etc.
Why do stars appear very small to us on Earth?
Stars appear small to us on Earth because they are extremely far away. The vast distance in space between us and the stars causes them to appear as tiny points of light in the night sky. Additionally, stars emit light that can be easily overwhelmed by the brightness of Earth's atmosphere and city lights, further contributing to their small appearance.
Why the moon stars and sun appear to change positions in the sky?
The sun and stars change positions because Earth moves
Compare the distance between two stars and the distance between two planets?
The distance between two stars is typically much greater than the distance between two planets. Stars are usually light-years apart, while planets in the same star system are typically within a few astronomical units of each other.
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.
Why do stars appear distant if you supposedly only see the light that they emit?
All sight its based on the light that objects either emit, reflect, or refract. The stars are little different in this regard. We judge distance using a number of different cues, a number of which indicate that the stars are far away.More distant objects will tend to appear smaller. The stars appear small.Any object that blocks a portion of the sky will block the stars from view, so we know the stars are more distant than those objects.When we move, objects we are looking at appear to change position relative to us. The farther away they are, the smaller the change. No matter how much we move there is no apparent change in the position of the stars, meaning they must be very far away.Indeed, the stars are much farther away than they appear to be as we are not able to perceive such distances directly.

What are clusters of stars that all appear to lie at the same distance from us?
Clusters of stars that all appear to lie at the same distance from us are called star clusters. There are two main types: open clusters, which contain young stars and are loosely bound together, and globular clusters, which contain older stars and are tightly packed.
What is the distance between star?
The distance between stars can be anything from light minutes to billions of light years.
