The surface of the asteroid appears completely covered in ice. More than one asteroid per year may be listed if its geocentric distance[note 2] is within a tenth of the lunar distance, or 0.10 LD. [82], In October 2013, water was detected on an extrasolar body for the first time, on an asteroid orbiting the white dwarf GD 61. On subsequent nights, the sky would be charted again and any moving object would, hopefully, be spotted. [61] Aside from the large crater at its southern pole, Rheasilvia, Vesta also has an ellipsoidal shape. [10] On Asteroid Day 2017, minor planet 248750 (discoverer M. Dawson) was officially named Asteroidday by the International Astronomical Union. Asteroid vs Earth è un film per la televisione a tema apocalittico del 2014 diretto da Christopher Ray. Some asteroids have moons or are co-orbiting binaries: Rubble piles, moons, binaries, and scattered asteroid families are thought to be the results of collisions that disrupted a parent asteroid, or, possibly, a planet. [11][12][13] In June 2018, the US National Science and Technology Council warned that America is unprepared for an asteroid impact event, and has developed and released the "National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. "Asteroid Day Special Event - Michael Busch and Peter Jenniskens (SETI Talks)" SETI Institute June 30, 2015. Passage is calculated by integrating the equations of motion. The uncertainty region is still somewhat large due to a short observation arc. The asteroid is most likely between 1 and 14 meters across, so would probably be detectable. The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA and 2019 MO are the only four asteroids discovered before impacting into Earth (see asteroid impact prediction). Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation. [91][18], In November 2019, scientists reported detecting, for the first time, sugar molecules, including ribose, in meteorites, suggesting that chemical processes on asteroids can produce some fundamentally essential bio-ingredients important to life, and supporting the notion of an RNA world prior to a DNA-based origin of life on Earth, and possibly, as well, the notion of panspermia. Giuseppe Piazzi found the first asteroid, in 1801. The radius of the Sun is 0.7 million km, and the radius of Jupiter (the largest planet) is 0.07 million km, both too small to resolve on this image. [26] This task required that hand-drawn sky charts be prepared for all stars in the zodiacal band down to an agreed-upon limit of faintness.
