Information about Uranus is limited. What we know is that the planet is composed mainly of water and ammonia ice, its diameter is about 51,000 kilometers, about four times that of the Earth, and its ...

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very ...

Researchers believe that 2017 OF201s highly eccentric orbit points to a chaotic origin, possibly caused by a gravitational ...

Uranus, the seventh planet in the solar system, located between Saturn and Neptune, has long been a mystery. But by analyzing observations made by NASA’s Hubble Space Telescope over a 20-year ...

In contrast, the transit approach is marked by geometric constraints: It requires a planet's orbital plane to align precisely with our line of sight—a rare occurrence for long-period systems.

If our solar system seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the moon moves through light and shadow, and the sun hangs in the sky. But ...

The orange dwarf Gliese 710 is expected to come within 0.1663 light-years or 10,520 astronomical units in about 1.29 million ...

New research on the orbits of these mysterious asteroids near Venus stress the need for better space rock surveillance.

Co-orbital asteroids – space rocks that travel alongside planets without fully orbiting them – are notoriously difficult to ...
