This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the ... 2008 TC 3: 2008-10-06 06:39 Mt. Lemmon Survey: 3.8 ...
Ceres makes up 40% of the estimated (2394 ± 5) × 10 18 kg mass of the asteroid belt, and it has 3 + 1 ⁄ 2 times the mass of the next asteroid, Vesta, but it has only 1 ⁄ 78 the mass of the Moon, and its surface gravity is 1 ⁄ 35 that of Earth (1 ⁄ 6 of the Moon's).
There is a point between the Earth and Sun where the gravities of the two bodies are perfectly in balance, called the Sun-Earth L1 Lagrange point (SEL1). It is approximately 1.6 million kilometres (1 million miles) from Earth, about four times as far away as the Moon, and is ideally suited for placing such a space telescope. [13]
An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years, NASA says — with the space agency saying it "no longer poses a significant ...
NASA said last week that there is currently a 2.3% (or 1 in 43) chance that the asteroid, dubbed 2024 YR4, will hit Earth on Dec. 22, 2032. While still tiny, that probability nearly doubled from ...
The highest estimate, by NASA's Jet Propulsion Laboratory, suggested a 3.1% chance the asteroid will hit Earth on Dec. 22, 2032, during a fleeting window of time in which the rock's orbit around ...
Discovered before it approached within 43,000 km of Earth on March 18, 2004. 2008 TC 3 ~0.003: October 6, 2008: First Earth-impactor to be spotted before impact (on October 7, 2008) (706765) 2010 TK 7 ~0.3: October 2010: First Earth trojan to be discovered 2014 RC ~0.017: September 1, 2014: Asteroid with fastest rotation: 16.2 seconds
Asteroid 2024 YR4 also rates 3 of 10 on the Torino Impact Hazard Scale, a method for astronomers to categorize and rate the threat of near-Earth objects. The scale ranges from 0 (no chance of ...
