Ceres: The Frozen Ocean World Between Mars & Jupiter — NASA’s Stunning Discovery!

In the vast expanse of the asteroid belt between Mars and Jupiter lies a celestial enigma: Ceres, the dwarf planet once dismissed as a barren rock. Recent discoveries by NASA’s Dawn mission have…

Comment l'astéroïde Vesta a failli être une planète ?

La sonde Dawn de la NASA qui a survolé Vesta a fourni des données qui montrent que cet astéroïde aurait devenir une planète naine si elle n'avait pas connu une origine complexe.

#DidYouKnow: #Pioneer 10 (originally designated Pioneer F) is an American space probe, launched in 1972 and weighing 260 kilograms (570 pounds), that completed the first mission to the planet Jupiter.

Between July 15, 1972, and February 15, 1973, it became the first spacecraft to traverse the #AsteroidBelt.

There are a LOT of moons out past the #asteroidbelt, so I'm going to break it down and only include a small selection.

In the thread I'll include some fun facts about the moons in case you need some help deciding!

#1682Karel, provisional designation 1949 PH, is a #stony Florian asteroid from the #inner regions of the #asteroidBelt, approximately 7.5 kilometers in diameter. It was discovered on 2 August 1949, by German astronomer #KarlReinmuth at #HeidelbergObservatory in southern Germany, and later named after the son of Dutch astronomer couple #Ingrid and #CornelisVanHouten.
Actually, Ceres Might Have Formed in the Asteroid Belt After All

Studies of the Dawn mission data taken at Ceres suggest that this dwarf planet may have formed in the Asteroid Belt, instead of farther out.

Dwarf planet #Ceres may have its origin in the #asteroidbelt, #mpsgoettingen scientists argue in a new paper in the Journal of Geophysical Research Planets. Yellowish bright material in #ConsusCrater is rich in ammonium and connected to Ceres’ curios #cryovolcanism, they find.

Dwarf planet Ceres: Origin in the asteroid belt?

Dwarf planet Ceres may have originated in the asteroid belt - and did not necessarily “migrate” there from the outer edge of the Solar System. This is indicated by bright, ammonium-rich deposits in Consus Crater, as a research team led by the Max Planck Institute for Solar System Research (MPS) in Göttingen argues today in the Journal of Geophysical Research Planets. The researchers analyzed observational data from NASA's Dawn space probe. Dawn had already discovered widespread ammonium deposits on the surface of Ceres years ago. According to some scientists, this suggests that frozen ammonium played a role in the dwarf planet’s formation. Ammonium is only stable in the outer Solar System. The new study finds another possibility: like other bright deposits on Ceres, the ammonium-rich material in Consus Crater could have been transported to the surface from within by Ceres' curious cryovolcanism.
