Proximity and properties
Wolf 359 is the fifth closest star to earth.[3] Located about 7.8 light years from earth, it is much smaller than earth’s star, Sol, at about 16% of Sol’s diameter. At the same distance from earth as Sol, it would be necessary to use a telescope to see its shape. It has approximately 9 % of Sol’s mass. Wolf 359 is also much dimmer at about 1/200,000th of Sol’s luminosity. It is too dim to see with the human eye and would cast only about 10 times the brightness reflected during a full moon on earth.[4][5][6]
Wolf 359 is a variable star [7] and flares periodically, growing dramatically in brightness and then receding in luminosity.[8]
Location
Wolf 359 is located on the celestial sphere coordinates[9] at right ascension 10 hours 56 minutes 29.2 seconds and declination +07 degrees 00 arcminutes 53 arcseconds.[10][11][12][13][14]

The correlating prime meridian runs through the vernal equinox (i.e. 0 hours 0 minutes & 0 seconds) marking the time from the vernal equinox in a 24-hour circle. So declination (latitude) for stars will directly correlate with that of earth and right ascension (longitude) correlates to a sphere that circumscribes earth’s orbital path around Sol.
