Bookmark or Share- Astronomers get first observations of smallest-known asteroidThe asteroid, named 2015 TC25, is also one of the brightest near-Earth asteroids ever discovered, reflecting 60 per cent of the sunlight that falls on it. Discovered by the University of Arizona’s Catalina Sky Survey last October, 2015 TC25 was studied extensively by a team led by Vishnu Reddy, an assistant professor at the University of ...
- 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 SpaceIn the Solar System, the snow line is thought to have been located at about 2.7 times Earth’s mean distance from the Sun, placing it in the middle of the main asteroid belt today. “Beyond the snow line, materials that were gaseous closer to the star condense into solid bodies, increasing the amount of material available to start the planet ...
- 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 ...
