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 ...
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.
Newton defined the force acting on a planet to be the product of its mass and the acceleration (see Newton's laws of motion). So: Every planet is attracted towards the Sun. The force acting on a planet is directly proportional to the mass of the planet and is inversely proportional to the square of its distance from the Sun.
(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 ...
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 ...
The Food and Drug Administration (FDA) is urgently warning consumers against using Neptune’s Fix — a pain supplement also known as “gas station heroin.” These supplements contain ...
There will be six more weeks of winter, according to America's favorite groundhog. Every Feb. 2, the marmot known as Punxsutawney Phil emerges from his burrow in western Pennsylvania and looks to ...
One simple visual mnemonic is to hold out both hands side-by-side with thumbs in the same direction (typically left-hand facing palm down, and right-hand palm up). The fingers of hand with palm down represent the terrestrial planets where the left pinkie represents Mercury and its thumb represents the asteroid belt , including Ceres .
