In 2017, Dawn confirmed that Ceres has a transient atmosphere of water vapour. [106] Hints of an atmosphere had appeared in early 2014, when the Herschel Space Observatory detected localised mid-latitude sources of water vapour on Ceres, no more than 60 km (40 mi) in diameter, which each give off approximately 10 26 molecules (3 kg) of water ...
The geology of Ceres is the scientific study of the surface, crust, and interior of the dwarf planet Ceres. It seeks to understand and describe Ceres' composition, landforms, evolution, and physical properties and processes. The study draws on fields such as geophysics, remote sensing, geochemistry, geodesy, and cartography (see Planetary ...
Bright spots on Ceres. Several bright surface features (also known as faculae) were discovered on the dwarf planet Ceres by the Dawn spacecraft in 2015. The brightest cluster of spots ("Spot 5") is located in an 80-kilometer (50 mi) crater called Occator. [1][2] The largest and brightest component of the cluster is in the center of the crater ...
e. The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere. Terrestrial planets are substantially different from ...
The weather service’s blizzard warning remains in effect for the greater Lake Tahoe area through 10 a.m. Sunday as the area prepares for “whiteout conditions” and “near zero visibility.”
One ski resort, Homewood Mountain Resort in the Lake Tahoe area, saw 87 inches of snow and was still without power on Sunday. (It planned to open at a delayed time Monday with limited trails.)
Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
A wet and windy storm is making its way through Northern California into the Sierra Nevada. Meteorologist Dakari Anderson with the National Weather Service said roughly 0.75 to 1.5 inches of rain ...
