    It might be a bit early to start packing your suitcase to relocate to a nearby habitable planet, but if your lifeclock holds out long enough, you might be a chosen passenger on a flight to this steamy, newly discovered super-Earth located just 90 light years from Earth. Granted, even though that's just a hop, skip, and a jump in the vast realm of interstellar distances, that still calculates out to a whopping 540 trillion miles!

    Eagle-eyed astronomers from Penn State University recently discovered this potential Goldilocks planet, officially catalogued as G 9-40b (shown below), that's estimated to be more than twice the size of our Big Blue Marble and possibly even as large as the gas giant, Neptune.

    The generically named G 9-40b was initially spotted by Kepler, NASA’s planet-hunting space telescope, during its K2 mission last year. But before you get too excited, you better bring along some 10,000 SPF sunscreen and a large water bottle, because the surface of this world is a toasty 5,600 degrees Fahrenheit!

    According to Gudmundur Stefansson, lead study author of a research paper published this month in The Astronomical Journal, it's “among the 20 closest transiting planetary systems known, and is currently the second closest transiting planet discovered by the K2 mission to date.”

    The planet's large transit depth, matched with the closeness and brightness of its M-type host star makes G 9-40b one of the most encouraging sub-Neptune-sized planets orbiting a Red Dwarf for successful transmission spectroscopy, with not only ARIEL — the ESA's Atmospheric Remote-sensing Infrared Exoplanet Large-survey — dedicated to investigating the atmospheres of exoplanets starting in 2028, but also the upcoming ground-based Extremely Large Telescopes currently under construction around the world.

    By employing The Habitable Zone Planet Finder (HPF), a low-mass planet-hunting instrument equipped on the 10-meter Hobby-Eberly Telescope at the McDonald Observatory in Texas, the team now believes that while it might not be exactly conducive to human colonization, G 9-40b could be worth a closer peek by NASA’s James Webb Space Telescope scheduled to blast off in March of 2021.

      That's the temperature of the star the planet is orbiting. Which is significant because that's 56% the temperature of our own sun. The Stefan-Boltzmann law states that the heat irradiating from a blackbody is proportional to the temperature to the fourth power, so that means it gives off only 10% of the heat our own sun does. The star is also a lot smaller.

      So even though this planet is a lot closer to than star, than the Earth is to the sun, it might not have a wild temperature. It just means that red dwarf stars have a goldilock zone much closer to them.

      The bigger problem is the amount of ionizing radiation it would be experiencing. That could be problematic, and might just keep those planets sterilized.

      Update:

      Here's the source article https://www.sciencedaily.com/release...0220130456.htm

      The calculated temperature of the planet at that distance is 319K +/- 28K

        Thank you for the reference.

          Even at a speed of 300 miles per minute, or 18,000 MPH, it would take over 3 million years to get there, so, other than scientific curiosity, I don't see the point.

            The article quoted in the OP does say the surface of the planet is 5600 degrees. Is that a mistake?

              Yes, That is a mistake. I always go directly to the sources, journalists usually get it wrong..

                Ok, thanks for clarifying. I thought that was awfully hot for a planet orbiting a red dwarf.
                And yeah, I think they need to have journalists with at least some scientific training be the ones to cover stories like this.

                  Journalists rarely have any relevant training on any topic. Remember the Gell-Man effect:

                  You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them.
                  In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.
                  Remember that you are dust and to dust you shall return.

                      Just a further caution, Science Daily is an aggregator of press releases, not a scientific source. While most universities try to make sure their press releases are accurate, there have been some rather dramatic exceptions. Plus they are under no obligations to present the caveats, limitations, etc. of the underlying research.

                      If you can find the paper, the abstract is almost always better than the press release.

                        Things don't need to have a practical application to be interesting. Where's your sense of scientific curiosity?

                          Usually at the end of the Science Daily article they'll have a link to the University Press release or the Abstract (and sometimes, the full paper).

                            Oh I find it interesting alright, but to suggest that 540 trillion miles away is tantalizingly close to the earth is a bit much. I'm of the belief that in the vast 4 billion light year expanse of this universes there is likely many such exoplanets capable of supporting life out there.

                              Typically, they're just republishing the press release verbatim. But yes, a link to the paper is helpful when available.
