     Earth-sized planet orbits brown dwarf

    Extra-Solar PlanetsAn Earth-sized planet has been discovered in orbit around a small, cool star, but at the Sun-Earth distance. Thus, its surface must be very cold. If the planet has as much water as the Earth, it will be an ice-ball, but this cannot be determined from the observations.

    The planet was discovered by "micro-lensing", where a foreground star - the one with the planet, acts as a lens to focus light from a background star, as it passes in front of it, leading to an increase in brightness in an Earth-based telescope. The planet also causes micro-lensing, so its presence can be detected by an additional brightening of the background star. The OGLD project watches the stars for just this effect, and found the planet which has, thus, been named: OGLE-2016-BLG-1195Lb
