Where is Gliese located?
Gliese 581: the mother star Gliese 581 is a red dwarf located 20.5 light-years from Earth, in the constellation Libra. Like other red dwarfs, it’s smaller and much dimmer than our sun. Scientists believe Gliese 581 is old — at least a few billion years — and relatively stable.
How long would it take the space shuttle to travel to Gliese 581g?
Current space shuttles don’t go much faster than 17,500 miles per hour. At that pace, it would take 766,000 years to get to Gliese 581 g—that’s more than three times longer than homo sapiens have been around.
How far away is Gliese 581c?

How long would it take to travel 100 million light years?
Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.
How big are the planets in Gliese 581?
The Gliese 581 planetary system now has four known planets, with masses of about 1.9 (planet e, left in the foreground), 16 (planet b, nearest to the star), 5 (planet c, centre), and 7 Earth-masses (planet d, with the bluish colour).
Is the planet Gliese 581g tidally locked?
Gliese 581g is one of the most Earth like planets detected in the habitable zone of its star. It is believed that Gliese 581g is tidally locked meaning that the same side of the planet is always facing its host star.
When was Gliese 581 discovered by the ESO?
Detected in August 2005 and using extensive data from the ESO/ HARPS spectrometer it was the fifth planet to be discovered around a red dwarf. Further observations by the same group resulted in the detection of two more planets, Gliese 581c and Gliese 581d.
Is there a message from Earth to Gliese 581c?
A Message from Earth (AMFE) is a high-powered digital radio signal that was sent on October 9, 2008 towards Gliese 581c. The signal is a digital time capsule containing 501 messages that were selected through a competition on the social networking site Bebo. The message was sent using the RT-70 radar telescope of Ukraine’s State Space Agency.
