Halley’s comet swings near Earth every 75 years. But debris left by the comet leads to two major meteor showers annually.

Astronomers from the Massachusetts Institute of Technology (MIT) have made an unusual discovery, finding a planet which is in the process of disintegrating. And as it decays, it is leaving behind a ...

EarthSky has reported that recent observations suggest the comet completes one orbit around the sun every 2.1 million years. As comets approach the sun, our star’s heat causes them to release ...

“Rather, the Sun and planets all orbit their common center of mass, known to scientists as the solar system barycenter.” That off‑center dance gives long‑period comets – and the dust grains they ...

Schematic diagram showing how the inclination of the comet orbit changes when the comet moves first around the barycenter of the solar system (*), then around the center of the Sun (•) when inside ...

Close to the sun, the comets shed particles called meteoroids. These meteoroids follow along with the comet, but some travel a shorter orbit and return early, others late, creating a meteoroid stream.
