Alpha Centauri, our nearest star system, is taking back its ancient moniker, Rigil Kentaurus, which means “foot of the centaur” in Arabic, according to Science, the online publication of the American Association for the Adancement of Science (AAAS). The newly named system is one of 227 stars and star systems that received name clarifications from the International Astronomical Union yesterday. That’s because many celestial bodies have multiple names, Space.com reports.


Scientists estimate the orange dwarf Alpha Centauri B system is slightly older than our 4.6-billion-year old solar system at anywhere from 4.8 billion to 6.5 billion years old. If life on a planet or moon in the habitable zone of Alpha Centauri B evolved similarly as it did on Earth, then primitive forms of life could already have flourished there when the young Earth collided with a Mars-sized object, forming our moon.

 

 

 

And, as all the world knows by now, Yuri Milner, the Russian billionaire investor, and Stephen Hawking have revealed plans for an interstellar mission, $100 million Breakthrough Starshot, that would launch chip-sized robotic probes at more than 25 percent the speed of light for 20-year journeys on the 25-trillion mile trip our nearest star system, Alpha Centauri.
