The orbital period is the time taken for a planet to make one complete circuit of the star. So, for example, two planets orbiting a star would be in a 2:1 resonance when one planet takes twice as ...

Resonance happens when planets or moons have orbital periods that are ratios of whole numbers. The orbital period is the time taken for a planet to make one complete circuit of the star. So, for ...

A planet-sized visitor possibly visited the solar system billions of years ago and permanently changed the cosmic neighbourhood by warping the orbital path of four outer planets of the system, a ...

Lava planets don’t play by the rules of our solar system. These scorching-hot worlds, some no bigger than Earth, orbit so ...

The newly outlined history of TRAPPIST-1 may, at last, explain how those patterns came to be. When planets form around a young star, their orbital periods often enter "resonances" with each other.

Orbital harmony limits late arrival of water on TRAPPIST-1 planets Fragile orbits of seven exoplanets could survive only limited early bombardment Date: November 25, 2021 Source: Rice University ...

That’s the case at least for a rare six-planet solar system whose discovery has wowed astronomers, even in an era when detecting planets around distant stars has become a common occurrence.

ETNOs should also be more or less on the same orbital plane as the Solar System planets. But observations of about a dozen ETNOs have suggested a quite different picture, the study says.

Orbital resonance can cause planets or asteroids to speed up or start to wobble. The star Gliese 876 has three planets with orbit period ratios of 4:2:1, just like Jupiter's three moons.
