So near, and yet so far.
Alpha Centauri is a double-star system with a much smaller, fainter, third companion star (Proxima Centauri) orbiting at a further distance away.
In galactic terms this is RIGHT NEXT to us, as close as you can POSSIBLY get, at 'only' a distance of about 4.3 light-years away from us.
Although in real terms 'close' and 'near' are hardly words to describe something that is....
*takes out calculator*
40,681,000,000,000 kilometres (25,278,000,000,000 miles) away.
Also, this planet is unfortunately only 0.04 AU from its sun (25 times closer than Earth) and so temperatures are estimated to be over 1,200°C. That's about three times hotter than even Mercury and Venus. So no likelihood of life.
But I still think this is significant news, and it should really inspire us to try to send a spaceprobe there, however long it may take. There may be something new about this planet we don't know about yet. Or there may be other smaller planets in this system at a greater distance away (which are unable to be detected as yet).
Can't wait for the time when humanity reaches for the stars.
