Ceres (minor-planet designation: 1 Ceres) is a dwarf planet in the asteroid belt between the orbits of Mars and Jupiter. Originally considered a planet, it was reclassified as an asteroid in the 1850s after the discovery of dozens of other objects in similar orbits. In 2006, it was reclassified again as a dwarf planet – the only one always inside Neptune’s orbit – because, at 940 km (580 mi) in diameter, it is the only asteroid large enough for its gravity to maintain it as a spheroid in hydrostatic equilibrium. — Wikipedia

    Psyche was the Greek goddess of the soul, born a mere mortal and later married to Eros, the God of love. Who knows why the Italian astronomer Annibale de Gasparis gave her name to a celestial object he observed one night in 1852?

    One of the most exciting findings from NASA's Dawn mission is that Ceres, the largest object in the asteroid belt that lies between Mars and Jupiter, hosts complex organics. The discovery of aliphatic molecules, which consist of carbon and hydrogen chains, in conjunction with evidence that Ceres has abundant water ice and may have been an ocean world, means this dwarf planet might have once […]

    One of the most commonly discussed challenges when starting our species' space exploration journey is how to get the resources necessary for life off of the Earth. Typically this is thought of as two things—water and oxygen, but, luckily, oxygen can be supplied by splitting apart a water molecule, so the most critical resource we could find in space is water.

    Impact cratering happens on every solid body in the solar system. In fact, it is the dominant process affecting the surfaces on most extraterrestrial bodies today.

  • Unknown class of water-rich asteroids identified
    on February 20, 2023 at 5:45 pm

    New astronomical measurements in the infrared range have led to the identification of a heretofore unknown class of asteroids. An international research team including geoscientists from Heidelberg University has succeeded in characterizing these small planets using infrared spectroscopy.

    In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter's icy moon Europa. These are none other than NASA's Europa Clipper and the ESA's Jupiter Icy Moons Explorer (JUICE), which will launch in 2024, and 2023 (respectively). Once they arrive by the 2030s, they will study Europa's surface with a series of flybys to determine if its interior […]

    on October 13, 2022 at 2:22 pm

    We have now discovered 30,039 near-Earth asteroids in the solar system—rocky bodies orbiting the sun on a path that brings them close to Earth's orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving.

    Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Subject to memorization in school and known as the definitive planetary lineup, Pluto was included in the list until the International Astronomical Union determined it did not meet qualifications in 2006.

    on August 1, 2022 at 1:37 pm

    For a long time, our view of Ceres was fuzzy, said Scott King, a geoscientist in the Virginia Tech College of Science. A dwarf planet and the largest body found in the asteroid belt—the region between Jupiter and Mars speckled with hundreds of thousands of asteroids—Ceres had no distinguishable surface features in existing telescopic observations from Earth.

    on May 19, 2022 at 2:55 pm

    When Sicilian astronomer Giuseppe Piazzi spotted Ceres in 1801, he thought it was a planet. Astronomers didn't know about asteroids at that time. Now we know there's an enormous quantity of them, primarily residing in the main asteroid belt between Mars and Jupiter.
