S/2023 U 1 is the smallest and faintest natural satellite of Uranus known, with a diameter of around 8–12 km (5–7 mi). It was discovered on 4 November 2023 by Scott S. Sheppard using the 6.5-meter Magellan–Baade Telescope at Las Campanas Observatory, Chile, and later announced on 23 February 2024. [1] It orbits Uranus in the retrograde ...
Uranus retrograde in Taurus will shift the collective consciousness when it begins its backward journey on August 28, 2023, at 10:39 p.m. ET. ... Uranus cycles cause cutting-edge changes in ...
Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which astronomy calls "ice" or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature (49 K (−224 °C; − ...
Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object (right figure). It may also describe other motions such as precession or nutation of an object's rotational axis. Prograde or direct motion is more normal motion in the same ...
The James Webb Space Telescope has snapped a glowing new portrait of Uranus that showcases the ice giant’s typically hidden rings, moons, weather and atmosphere — features that were nowhere to ...
Skywatchers can watch as the moon blocks Uranus from view on Wednesday, Sept. 14 in an event called a lunar occultation.
Parallax is the apparent change of the position of an object, measured in seconds of arc, caused by the change of position of the observer of that object. As the Earth orbits the Sun, every star is seen to shift by a fraction of an arc second, which measure, combined with the baseline provided by the Earth's orbit gives the distance to that star.
True polar wander. True polar wander is a solid-body rotation of a planet or moon with respect to its spin axis, causing the geographic locations of the north and south poles to change, or "wander". Unless the body is totally rigid (which the Earth is not), its stable state rotation has the largest moment of inertia axis aligned with the spin ...
