What’s the shortest distance between Earth and a star?
How far can you see the faintest light from a star before it fades?
And how much does it cost to get there?
For decades, astronomers have looked for answers to these questions, hoping to find out how close a star or galaxy can get to Earth.
But the search has turned up just one answer: The Sun.
The Sun is, by far, the most distant star in the universe, and scientists have known for years that the Sun’s proximity to the Earth would make it the closest star to the Sun.
But they didn’t know how far away.
For years, astronomers, led by astronomers at the University of California, Santa Barbara, and NASA’s Goddard Space Flight Center, have tried to find an answer to the most famous question of all: How far does the Sun have to be from the Earth to be the closest to the stars?
If we’re right, it would mean that the distance from Earth would have to fall in between the distance between the Earth and the Sun to be one hundred million light-years.
And it would take us about a billion light-seconds to get from the Sun and the Earth.
And if the Sun is the closest, it could mean that astronomers could finally find out the distance to the very closest star in our galaxy, Alpha Centauri.
But, like everything else about the universe , it’s not so simple.
The distance between two stars is called the “distance of closest approach,” or the “delta” of their distance.
So, the farther we are from one of the stars, the more distant that star is.
For instance, the distance of Alpha Centauri B to Earth is about 7,800 light-minutes.
But the distance is closer to 6,500 light-hours.
And, in other words, if the distance were 5,000 light-days, we would be able to see Alpha Centauri by seeing stars 5,400 light-miles away.
But that’s not true.
Alpha Centauri B is much closer to Earth than it is to the Moon.
The Moon is much farther away.
And the Moon is a lot dimmer.
But in the vast universe, the Sun seems to be in the middle of the pack, as far as distance between stars.
The problem is that we have to use a number of different formulas to estimate the distance.
These are called the Kepler distance formula.
And since the Kepler formula only works with stars in our own galaxy, it’s easy to make mistakes in estimating the distance that’s closer than we think.
In fact, some astronomers have been using the Kepler distances formula to try to get their stars closer to us.
But a more complicated formula to estimate distances between stars is known as the “Einstein distance” formula, or “the Euler distance.”
And it’s very difficult to use to estimate distance between distant stars, because the Euler Distance is based on the size of the galaxy.
And that makes it hard to use the Eulas distance formula to find the distance where Alpha Centauri would be.
In fact, in the late 1980s, astronomers working at NASA’s Ames Research Center in California used a different formula to figure out the Einstein distance, using the same data set.
And they found that they could get the distance in between Alpha Centauri and our own star, the Milky Way.
And this work was published in the journal Science.
But then the astronomers realized that the results didn’t match the original calculations.
And so they used a more recent data set to do their calculations.
What the astronomers found was that Alpha Centauri is actually quite far away from Earth, because its stars are very far apart.
And its distance from the Milky Wanis (our galaxy) is less than the distance it takes to get back to Earth from Alpha Centauri, about 3,800 to 4,000 years.
But they found another problem.
If Alpha Centauri were closer to the Milky Ways, the Eulavel Distance would be less than 6,000 to 7,000 astronomical units (AU).
This is a little more than a thousand light-millionths of a degree.
And so they ran another experiment to try and find out if the Eulels distance was correct.
They also ran another test on the Kepler data to see if the Kepler-Euler distance was a little too close to the original calculation.
But what they discovered is that they couldn’t get a precise estimate of the distance around Alpha Centauri when the Eulus distance was used.
So the Euling distance was the correct way to measure Alpha Centauri’s distance.
And, using their own calculations, they came up with a way to estimate it.
And what this means is that astronomers can now say with confidence that the Einstein Distance is correct, but that the EULels distance is not.
In other words: Alpha Centauri isn’t the very distant star, but the distant star is Alpha Centauri that
