How close can two stars be together?
How close can two stars be together?
However, the two stars are really not very close to each other at all. The two stars in Alpha Centauri are typically somewhere between 1 billion miles and three billion miles apart. That’s enough space to fit at least half our solar system between the two stars.
What is the average distance between stars?
Although galaxies look like dense concentrations of stars they are really very empty. In the Milky Way, the average distance between stars is about 5 light years, or 30 trillion miles.
How far away is 5 light years?

How far apart are stars in the sky?
The night sky is full of stars, and those stars are incredibly distant. The distances are measured in light years, which corresponds to the distance travelled by light in one year. That’s about 9 trillion km.
Are all stars at the same distance from Earth?
So no, the fact that stars all look like a dot or a point of light does not mean they are all at the same distance. The Sun is at a mean distance of one Astronomical unit (AU, about 150 million kilometres or 8 light-minutes) from Earth. The next nearest star is Proxima Centauri at a distance of approximately 270,000AU (or more than 4 light-years).
What is the size of the nearest star to the Sun?
The next nearest star is Proxima Centauri at a distance of approximately 270,000AU (or more than 4 light-years). If it were the size of the Sun (it is actually smaller) it would look 270 thousand times smaller or, as you say, like a dot.
What is the closest pair of stars to each other?
The closest pair that I’m aware of is HM Cancri, with a period of only 5 minutes; the stars are 80,000 km from each other (closer than the earth and the moo The closest stars are binary stars, spinning around each other. They’re so close to each other that they appear as a single star to the naked eye.
How far apart are the planets in the Solar System?
There is a huge amount of different in the distances between the planets depending on their position on their orbit path. The table below shows the eight planets and the average distance between them. The AU column is the distance in astronomical units. 1 AU is the distance from the Sun to Earth, which is 149,600,000 km.
