2D Simulation of Solar System using pure ES 6. Orbits computed with real coefficients (AU scaled to pixels). Main belt asteroids' eccentricities generated with Rayleigh distribution. Welcome to Space ...

A tiny asteroid loitering in a near-Earth orbit for a few months last year may have an intriguing origin on our Moon. Its characteristics led scientists to ask: is it a chip off the old lunar block, ...

While this may sound like an immense distance, it's pretty close on a cosmic scale: the moon ... Earth Object or NEO, which are defined as objects that come within about 120 million miles of the ...

Oxygen isotope identity of the Earth and Moon with implications for the formation of the Moon and source of volatiles. Proceedings of the National Academy of Sciences , 2024; 121 (52) DOI: 10.1073 ...

The prevailing theory had been that the moon was the result of a collision between early Earth and the protoplanet Theia. New measurements indicate that the moon formed from material ejected from ...

In January 2025, NASA’s Goldstone Solar System Radar is closely tracking asteroid 2024 PT5 during its nearest approach to Earth, a distance still five times farther than the Moon. First spotted in ...

A recently discovered comet is making a bright debut on Earth this month, and with some effort, skygazers might be able to see Comet ATLAS. Comet C/2024 G3 ATLAS was discovered in April 2024 using the ...

As a volcanic eruption darkened the sun roughly 4,900 years ago, a Stone Age culture sacrificed hundreds of decorated stone plaques to try to coax it back. A trove of engraved stones unearthed ...

On Jan. 15, the sun will oppose Mars retrograde, triggering a cosmic standoff between your ego and your emotions. This is the kind of transit that could make you feel like you’re caught in a tug ...

While a solar eclipse involves the moon passing between the sun and the Earth, casting a shadow across our planet, a lunar eclipse involves the Earth passing directly between the moon and the sun.

Two lunar landers built by private companies in the US and Japan have left Earth aboard a SpaceX rocket as part of a rideshare to the Moon. The Falcon 9 took off from the Kennedy Space Center in ...
