Gliese 445 (Gl 445 or AC +79 3888) is an M-type main sequence star in the northern part of the constellation Camelopardalis.

It is currently 17.1 light-years from Earth and has an apparent magnitude of 10.8. It is visible from north of the Tropic of Cancer all night long, but not to the naked eye.[10] Because the star is a red dwarf with a mass only a quarter to a third of that of the Sun, scientists question the ability of this system to support life.[10] Gliese 445 is also a known X-ray source.[11]

The Voyager 1 probe will pass within 1.6 light-years of Gliese 445 in about 40,000 years.[12]

Solar encounter

While the Voyager probe moves through space towards a 1.6-light-year minimum distance from Gliese 445, the star is rapidly approaching the Sun. At the time the probe passes Gliese 445, the star will be about 1.059
