The evidence suggests that Planet “g” is a rocky planet with a diameter about 1.2 to 1.4 times larger than Earth’s, they said in a paper posted online at arXiv.org, a pre-print archiving service. It will be published in the Astrophysical Journal.
The planet’s mass means its gravity would be the same as, or slightly higher than, Earth’s, and a person could easily walk upright, Vogt said in a release. That is also enough gravity to hold onto an atmosphere.
The planet is “tidally locked” to the star that it orbits every 37 days, which means one side is always facing the star and one side faces away in perpetual darkness (similar to the way the Earth always faces the same side of the moon). That means that even though the average surface temperature is likely between -31 C and -12 C, one side is extremely hot, and the other side is always freezing cold.
Seems like it’d be a very slim habitable zone with horrendous weather patterns. You may have boiling oceans on one side feeding torrential downpours composed of whatever chemicals right onto the habitable zone.
That’s 175,200,000,000,000 kilometres (roughly 108,887,507,768,800 or 108 trillion miles). Our state-of-the-art shuttles, which are not built for interstellar travel, would take 707,058 years to reach Gliese 581.
I would say that the chances for life on this planet are 100 percent. I have almost no doubt about it," Steven Vogt, professor of astronomy and astrophysics at University of California Santa Cruz, told Discovery News.
Steven “The Faith-Based Huckster” Vogt once again…
We don’t even know about everything under our own oceans on this planet and yet he chirps, “I would say that the chances for life on this planet are 100 percent.”
