Vega
Vega, also designated α Lyrae (Latinised to Alpha Lyrae, abbreviated Alpha Lyr or α Lyr), is the brightest star in the constellation of Lyra, the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. It is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood.
NR Canis Majoris
NR Canis Majoris will eventually become the brightest star in the sky 2.6 million years from now to 3 million years from now, one of 4 different stars in Canis Major to hold that title (Alpha Canis Majoris, Beta Canis Majoris, and Epsilon Canis Majoris). During this period, NR Canis Majoris will be only 14 light years away and appear at -0.88 magnitude, about the same as Canopus today.
