For gaseous or fluid bodies, such as stars and giant planets, the period of rotation varies from the object's equator to its pole due to a phenomenon called differential rotation. Typically, the stated rotation period for a giant planet (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as determined from the rotation ...
(455502) 2003 UZ 413 (provisional designation 2003 UZ 413) is a trans-Neptunian object (TNO) with an absolute magnitude of 4.38. [5] It is in a 2:3 orbital resonance with Neptune, thus it is classified as a plutino. [3] There are indications it may be dense enough to be a dwarf planet. It was given the minor planet number 455502 on 22 February ...
The 3:4, 3:5, 4:7 and 2:5 resonances are less populated. [150] Neptune has a number of known trojan objects occupying both the Sun–Neptune L 4 and L 5 Lagrangian points—gravitationally stable regions leading and trailing Neptune in its orbit, respectively. [151] Neptune trojans can be viewed as being in a 1:1 resonance with Neptune.
They recreated Neptune's conditions at Stanford's SLAC Laboratory and successfully observed the formation of diamond rain, thanks to the help of some very powerful lasers. Scientists recreate ...
According to Copernicus: [3] [4] The planetary orbit is a circle with epicycles. The Sun is approximately at the center of the orbit. The speed of the planet in the main orbit is constant. Despite being correct in saying that the planets revolved around the Sun, Copernicus was incorrect in defining their orbits.
Scientists have finally discovered how sheets of diamond rain form on the ice giants, Neptune and Uranus. The answer could explain why Neptune’s core is hot.
Venus rotates clockwise, and Uranus has been knocked on its side and rotates almost perpendicular to the rest of the Solar System. The ecliptic remains within 3° of the invariable plane over five million years, [2] but is now inclined about 23.44° to Earth's celestial equator used for the coordinates of poles. This large inclination means ...
Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. [a] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 9 km).
