Planetary scientists have long been interested in a return visit to Neptune, but the planet is so distant that an orbiter or lander mission is next to impossible. While the New Horizons spacecraft ...

Neptune, Jupiter, Uranus and Mercury will be visible in the eastern night sky. All five planets will be spread out along the ecliptic—the plane of the solar system upon which all planets orbit ...

Kuiper Belt, well past the orbit of Neptune (artistic illustration). There may be an undiscovered planet in the outer solar system whose presence is revealed by the strange orbit of objects beyond ...

A team of international astronomers has discovered a new super-Neptune exoplanet, named TOI-5005 b, orbiting a star similar ...

Researchers from Warwick and other universities examined Neptunian exoplanets -- these planets share similar characteristics to our own Neptune, but orbit outside of our solar system. Scientists ...

Neptune’s Tides. McCord’s calculations seem to support what other scientists have suspected. Long ago, as it sank from a higher orbit, Triton passed close to Nereid. The smaller moon ...

In general, as the distance from the Sun increases: the temperature decreases, for example, Mercury is 430 °C whereas Neptune is -200 °C the time taken to orbit the Sun increases, for example ...

In general, as the distance from the Sun increases: the temperature decreases, eg Mercury is 430°C whereas Neptune is –200°C the time taken to orbit the Sun increases, eg Mercury orbits once ...
