Planets. The temperature estimate is ~ 10 K lower than ours. Gliese 581g has temperatures ranging between minus 24 degrees Celsius to 10 degrees Celsius, which is not too hot and not too cold as far as harbouring life matters. This makes it the most Earth-like Goldilocks planet found outside the Solar System and the exoplanet with the greatest recognized potential for harboring life. They said that the planet, named Gliese 581b, has a size close to the size of Neptune (the eighth planet in our solar system). This makes it the 89th closest known star to the Sun. Again with their site in the homepage being. The new planet designated Gliese 581g has a mass three to four times that of Earth and orbits its star in just under 37 days. Because Gliese 581g orbits close to its star (0.15 AU) and the system is at least 7 billion years old, the planet is tidally locked with its star. Astronomers have discovered some planets that orbit Gliese 581. In 2009, Gliese 581 is the 87th closest known star. Gliese 581g is one of two new worlds the team discovered orbiting the red dwarf star Gliese 581, bumping that nearby star's family of planets to … Gliese 581 is a red dwarf located in the constellation Libra to 20.5 light years from us. – Gliese 581 g is even closer an Earth analog than the ESI suggests, since it is so sensitive to temperature. This means that the planet rotates once every 37 days, the same period over which it revolves around its star. Architecture of the system This list shows all planetary and stellar components in the system. Gliese 581 is an M-class red dwarf star that is not far from the Earth. The astronomers agree that four of the planets are real, but some think there are two more planets. It is also known as HO Librae, GL 581, or GJ 581. Average surface temperature - between -24F and 10F (-31C and … In the 2005, scientists found a planet orbiting Gliese 581. It gives a quick overview of the hierarchical architecture.
