The extrasolar planets, or exoplanets, that swirl around the star TOI-201 have orbits that are changing so rapidly that astronomers can see the changes in real time. The behavior of the system, located around 370 light-years from Earth, is something scientists have never seen before.
TOI-201 is 1.3 times the mass of the sun and also has a diameter of 1.3 times the size of our home star. The exoplanets that orbit the star include a rocky super-Earth with six times the mass of our planet that has a year lasting just 5.8 Earth-days. Its planetary siblings are a gas giant with half the mass of Jupiter, completing an orbit every 53 days, designated TOI-201b, and another gas giant that has 16 times the mass of Jupiter that completes an orbit every 2,883 days (about 7.9 years).
