Mercury's spin and its orbit around the Sun are tied to each other in a unique arrangement. According to a set of calculations, random asteroid impacts may have aided the planet's evolution into the ...

Hi’iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have ...

Earth's orbital period around the Sun is 365 days, while its rotational period is 24 hours. The Moon's orbital and rotational periods are both approximately 27.3 days, resulting in synchronous ...

Our Earth is well-suited for life because it is perfectly spit-roasted by our Sun thanks to our planet’s axial rotation — but other planets aren’t so lucky. A new study from Peking University reveals ...

In the early morning of April 10, the 100-meter-high main tower of the Longyan Bridge in Fujian, constructed by China State Construction Engineering Corporation (CSCEC), completed a counterclockwise ...

Newly obtained image of Earthrise over the north pole of the Moon, taken by the Lunar Reconnaissance Orbiter spacecraft. The LRO Camera Team recently released a newly obtained, beautiful image of the ...

The orbits of Pluto's four smallest moons are even more chaotic than scientists had expected, according to new results from the New Horizons mission, which made a close flyby of Pluto in July. "The ...
