The ring was first formally proposed after 21 impact craters from the meteor event were found to be located along a straight band around the Earth's equator. [10] [11] Andrew G. Tomkins, [9] Erin L. Martin [9] and Peter A. Cawood, [9] working with Monash University, released a study in September 2024 that gave evidence on the existence of the ...
A 2024 study suggests that Earth may have had a ring system for a period of 40 million years, starting from the middle of the Ordovician period (around 466 million years ago). This ring system may have originated from a large asteroid that passed by Earth at this time and had a significant amount of debris stripped by Earth's gravitational pull ...
An artist's impression of Rhea's rings. The density of the particles is exaggerated greatly to aid visibility. [1] Rhea, the second-largest moon of Saturn, may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk. This would be the first discovery of rings around a moon.
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
Although the Moon is Earth's only natural satellite, there are a number of near-Earth objects (NEOs) with orbits that are in resonance with Earth. These have been called "second" moons of Earth or "minimoons". [2] [3] 469219 Kamoʻoalewa, an asteroid discovered on 27 April 2016, is possibly the most stable quasi-satellite of Earth. [4]
Due to Earth's varying distance from these planets (as well as their distance to the Sun), the limits at which we are able to detect new moons are very inconsistent. As the below graph demonstrates, the maximum absolute magnitude (total inherent brightness, abbreviated H) of moons we have detected around planets occurs at H = 18 for Jupiter, H ...
Research reveals ancient Earth may have had temporary polar moons formed after a collision with Theia, reshaping our understanding of early planetary history.
The four giant planets have planetary rings, thin discs of tiny particles that orbit them in unison. [47] As a result of the formation of the Solar System, planets and most other objects orbit the Sun in the same direction that the Sun is rotating. That is, counter-clockwise, as viewed from above Earth's north pole. [48]
