Scientists will never know the farthest star from Earth, as the star is so far away that its light has not, nor will ever, have enough time to reach Earth. Even the stars within the visible universe are far too numerous to count, but the farthest one that humans have ever detected is about 55 million light years away. This incredibly distant star is called SDSS J 122952.66 +112227.8.Continue Reading
The farthest object that scientists have discovered is a galaxy by the name of UDFj-39546284. This is a very early galaxy that is about 13.2 billion light years away. However, scientists are constantly improving their visualization technology, and they hope to find even more distant objects in the near future.
The star Deneb is the farthest star that can be easily seen with the naked eye. It is thought to be between 1,400 and 3,000 light years from Earth. Deneb is one of the brightest in the northern sky and is part the constellation Cygnus, the Swan.
The Sun is the closest star to the planet Earth. The Earth orbits the Sun at a distance of about 93 million miles. Scientists use this distance as a convenient unit of measure for astronomical distances. Scientists call this distance one “astronomical unit,” often abbreviated AU.Learn more about Astronomy
