Find out how to look for exoplanets by looking for wobbly stars, transit effects, and other ways. An exoplanet is a planet outside our solar system, usually orbiting another star. They are also sometimes called "extrasolar planets," "extra-" implying that they are outside of our solar system. The first exoplanet to burst upon the world stage was 51 Pegasi b, a “hot Jupiter” 50 light-years away that is locked in a four-day orbit around its star. The watershed year was 1995. All of a sudden, exoplanets were a thing. But a few hints had already emerged. A planet now known as Tadmor was detected in 1988, though the discovery …Apr 13, 2022 · This is called “transit method.”. Once detected, the planet's orbital size can be calculated from the period (how long it takes the planet to orbit once around the star) and the mass of the star.
