The question in your title and the questions in the body are two different questions! The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far along Earth's celestial equator the star is. But since even the nearest stars are hundreds of thousands of times farther away than the diameter of Earths orbit, the parallax shifts are tiny, and can only be measured with precise instrumentation. gads_event = event; Life's not easy for Doug Eiffel, the communications officer for the U.S.S. However, the probe will most likely be dead and silent as it flies by. Why Didn't the Borg Attack the Federation Earlier? To compare different stars' actual brightness, you would best use Absolute rather than Apparent Magnitude. Wolf 359 exhibited hundreds of flares in the K2 data, each more energetic than the Sun's Carrington flare, the . Its mass is just above the lowest limit (0.08 solar masses) at which a star is massive enough to ignite stable hydrogen burning in its core.
