Neptune is also the farthest planet in the solar system from Earth and orbits at a distance of between 2.7 billion miles (4.3 billion kilometers) and 2.9 billion miles (4.7 billion km) from our ...

Beyond Neptune, a celestial object puzzles astronomers with its synchronized motion with the giant planet. Its inclined orbit ...

From the outskirts of the sun’s orbit, Neptune bathes in only 0.1 percent of the intensity of sunlight that we get on Earth. Yet despite the distance between them, the sun still holds sway over ...

A team of astronomers discovered a strange object in the outer solar system that is in a resonant orbit with Neptune.

A lone body, making one passage around the Sun for every ten by Neptune, is rewriting the rules of planetary dynamics in the ...

This object is the first confirmed body that orbits the sun once for every ten orbits Neptune completes.

Astronomers have discovered a bizarre object in the outer solar system, 2020 VN40, that dances to Neptune’s gravitational beat in a never-before-seen rhythm. It’s the first of its kind, orbiting the ...

Neptune cloud coverage as seen by the Keck Observatory. The solar cycle is a period when the Sun's magnetic field flips every 11 years. This causes levels of solar radiation to fluctuate.

Over the past few years, the white clouds that usually shroud Neptune’s surface have disappeared, and it may be because of changes in the sun’s activity over its 11-year cycle ...

The astronomers then compared that data to the timeline of the Sun’s solar cycle, an 11-year period in which the Sun’s solar activity slowly ramps up until it eventually peaks.
