But the Earth orbits the sun (which is slightly more massive than rho Coronae Borealis) every 365 days. Usually astronomers find small Earth-like planets with orbits less than 40 days around small stars. ![]() “This one study doesn’t tell us, but at least it tells us that we can start seeing whether or not there’s planets. But we haven’t been able to find small planets like Earth in long-period orbits around these types of stars before,” Brewer explained. This is exactly the kind of star that we want to be looking around. “If we’re going to find an Earth-like planet, it has to be around a sun-like star. But the new survey discovered a third planet that’s much smaller (four times the mass of the Earth, which is considered small) with a 13-day orbit and a fourth planet that’s similar to Neptune (20 Earth masses) with a 280-day orbit. Two large planets were already known to orbit this star. ![]() The new exoplanets orbit rho Coronae Borealis, a star about the same size as our sun. The findings have been accepted to the Astronomical Journal but the preprint is already available on arXiv. The new exoplanets are the first to be discovered in the 100 Earths Survey, a project led by Brewer that uses an extremely precise new tool to detect planets previously beyond scientists’ reach. Their latest report describes the detection of two new exoplanets in what was believed to be a two-planet system. He and his collaborators are inching closer to their goal with their new discovery. He’s the latest in San Francisco State’s long list of planet hunters hoping to find new planets comparable to our Earth. Have you ever considered the stars in the night sky and wondered how many are orbited by planets like ours? Astronomy and Physics Assistant Professor John Michael Brewer has … and he’s getting answers. And in February, it was on The Princeton Review’s 2023 Best Business Schools list. 15 on a US News and World Report list of Top Performers on Social Mobility. 5 on the Wall Street Journal’s list of Top 20 Public Colleges for Accounting Students. This isn’t the first time SF State has been prominent in college rankings this year. “The school takes pride in its entertainment-oriented coursework, such as cinema, music, and writing, and counts an impressive number of Oscar, Emmy and Pulitzer Prize nominees among its alumni,” Money’s editors wrote. And alumni accomplishments were cited, as well. This year’s Money review cited a strong commitment to community service as “a key feature of San Francisco State’s programs.” It also mentioned the opportunities for field work at the University’s Estuary & Ocean Science Center and Sierra Nevada Field Campus. In 2022, SF State was #75 on Money’s list of Best Colleges in America, Ranked by Value. Of 736 colleges reviewed, only 34 received 5-star ratings, and 190 were given 4.5 stars. ![]() colleges, this year’s list used a star system. Though in the past Money assigned numbered ranks to U.S. Money based its rating on SF State’s quality of education, affordability and outcomes compared to other universities. SF State has been awarded a 4.5 out of 5 star rating by Money magazine in its Best Colleges in America 2023 list. ![]()
