Bookmark or Share- New Saturn-mass exoplanet discovered around a pair of starsThe planet orbits roughly 300 million miles from the stellar duo, about the distance from the asteroid belt to our Sun. It completes an orbit around both stars roughly every seven years. The two red dwarf stars are a mere 7 million miles apart, or 14 times the diameter of the Moon’s orbit around Earth.
- Ceres’ organic material most likely made by dwarf planetThe SwRI have investigated the possibility of a comet or an asteroid transporting the organics, but the results point towards the substance being most likely native to the dwarf planet. “The discovery of a locally high concentration of organics close to the Ernutet crater poses an interesting conundrum,” says Dr. Simone Marchi, a principal ...
- Most common ‘outer planets’ probably like Neptune - All About SpaceA new statistical study of planets found by a technique called gravitational microlensing suggests that Neptune-mass worlds are likely the most common type of planet to form in the icy outer realms of planetary systems.
- NASA’s Dawn spacecraft has gone silent - All About SpaceIn 2011, when Dawn arrived at Vesta, the second largest world in the main asteroid belt, the spacecraft became the first to orbit a body in the region between Mars and Jupiter. In 2015, when Dawn went into orbit around Ceres, a dwarf planet that is also the largest world in the asteroid belt, the mission became the first to visit a dwarf planet ...
- An impact crater on Earth can be traced back to the asteroid belt ...The meteorites reflect light much like asteroid Vesta and its family of Vestoids. 525-kilometre (326-mile) Vesta is the second largest body in the asteroid belt. The 0.8 to eight kilometre (0.5 mile to five mile) sized Vestoids are fragments from a massive collision that created the Rheasilvia impact basin on Vesta.
