  Los Angeles CA (SPX) Mar 11, 2025 The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of exoplanets - from the size of Jupiter down to the size of Mars - and shown that small planets have nearly circular orbits, while giant planets have orbits about four times more elliptical than sm ... read more |
