Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
The original mandate to NASA given by the United States Congress in 1998 was to detect 90% of near-Earth asteroids over 1 km (0.62 mi) diameter (that threaten global devastation) by 2008. [20] NASA's PDCO considers objects with a diameter of at least 1 km (0.62 mi) capable of creating an impact crater at least 10 km (6.2 mi) across and causing ...
Dinkinesh was discovered on 4 November 1999 by the Lincoln Near-Earth Asteroid Research (LINEAR) sky survey at Socorro, New Mexico. [2] The discovery observations were published by the Minor Planet Center (MPC) on 23 November 1999 and the asteroid was given the minor planet provisional designation 1999 VD 57, which describes its discovery year, month, and discovery order within the month.

2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.
Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth. Rows highlighted grey indicate a planet or main-belt asteroid
The mission has already discovered fascinating new secrets about the life-giving star, a 4.5 billion-year-old ball of hydrogen and helium that’s about halfway through its lifespan.
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.

2023 BU is a near-Earth object that passed 9,967 ± 1 km (6,193.21 ± 0.62 mi) from the centerpoint of Earth around 27 January 2023 00:29 UT. [3] Since Earth's radius is about 6,378 km (3,963 mi), it was expected to pass approximately 3,589 ± 1 km (2,230.10 ± 0.62 mi) from the surface of Earth over the southern tip of South America. [7]
