For this reason, astronomers regularly look for orbital changes each time comets return near the Sun and update those orbits ...

Researchers say there’s a 1.3 percent chance that the space rock 2024 YR4 could strike our planet — but not until December ...

A newly-discovered comet might light up the night sky in the coming weeks, possibly shining even brighter than the planet Venus. The comet, named Comet ATLAS (C/2024 G3), is making a beeline for the ...

Michigan State University and NASA researchers discover seven dark comets that reveal new solar system secrets.

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's ...

Comet and asteroid perihelions Unlike the fairly circular planetary orbits, comets and asteroids tend to follow orbits with very high eccentricities. They emerge from the farthest reaches of the ...

When material is blown off the comet's surface, there is a rocket-like recoil that provides the nongravitational acceleration on top of their orbits, which are already set by the gravitational ...

The comet orbits the sun every 5.3 years. Scientists think a larger comet was gravitationally bound into a short orbit by the sun around 2000 BC. The comet left behind meteors for years before ...

Avi Loeb shares the story of how a Tesla Roadster had some astronomers convinced for a time that they had discovered a new ...

For this reason, astronomers regularly look for orbital changes each time comets return near the Sun and update those orbits as needed, leading to reference catalogs listing multiple orbits for ...
