A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...
Astronomers have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the ...
Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...
The EXOEarths team (Centro de Astrofisica da Universidade do Porto – CAUP), in collaboration with Geneva University, did a joint analysis of data from the HARPS spectrograph and the Kepler satellite.

Eccentricities of orbits point to significantly different upbringings for small and large planets
UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of ...
Kepler-30 is a star of nearly solar mass and radius, but it is probably younger than the Sun, judging from its faster rotation and more prominent starspots 8. The starspots are crucial to measuring ...
