Despite ghost lore, the Star Hill lookout in Remson is part of the new widened path and a great spot to witness the 34 seconds of totality from 3:24:47 – 3:25:21 p.m.
More than one asteroid per year may be listed if its geocentric distance [note 1] is within a tenth of the lunar distance, or 0.10 LD. For comparison, since a satellite in a geostationary orbit has an altitude of about 36,000 km (22,000 mi), then its geocentric distance is 0.11 LD (approximately three times the width of the Earth).
The asteroid's path drastically will be altered by Earth's gravity once it zips by. Instead of circling the sun every 359 days, it will move into an oval orbit lasting 425 days, according to NASA.
The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] 2024 indicates the discovery year, the first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December) of that year, and "R 4" indicates that it was the 117th provisional ...
The fastest asteroid to pass within 1 LD of Earth in 2023 was 2023 TK 15 that passed Earth with a velocity with respect to Earth of 21.95 km/s (49,100 mph), [4] while the slowest bypass within lunar distance was that of 2023 XQ 16 at a velocity with respect to Earth of 3.16 km/s (7,100 mph). [5]
An asteroid the size of a football stadium will zip past Earth today. The asteroid, 2022 BH7, is one of four near-Earth objects making a close approach this weekend. (Fear not. ... In total, two ...
The comet was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey on 5 April 2024, in images obtained with a 0.5-m reflector telescope located in Río Hurtado, Chile. The comet at the time was a magnitude 19 object about 4.38 AU (655 million km) from Earth. Further observations indicated it had a diffuse coma about 4. ...
