Experts have learned what they say could be the smallest totally free-floating earth ever detected. The planet was uncovered by College of Warsaw researchers in the center of the Milky Way, and is approximated to be in between the size of Earth and Mars.
Free-floating or “rogue” planets do not orbit stars, and are notoriously hard to detect. The scientists used a approach identified as “microlensing,” which lets experts to uncover planets they wouldn’t or else be able to notice. “Rogue planets never orbit stars, they are gravitationally unattached to any host star. They will not emit any noticeable radiation, so they can’t be detected making use of conventional astrophysical methods,” Przemek Mroz, 1 of the co-author’s of the paper stated on Twitter.
“The lens is one of the best candidates for a terrestrial-mass rogue earth detected to day. It may have been a planetary embryo that was ejected from its guardian planetary process.”
Scientific American notes that scientists continue to need to have to validate the planet’s “rogue” position, but that it would signify the smallest cost-free-floating earth ever uncovered. NASA, which is also functioning on a telescope that will be ready to observe totally free-floating planets, has claimed that rogue planets can assist us understand about how planets are shaped.
