2023 DZ 2 is an asteroid roughly 70 meters in diameter, classified as a near-Earth object of the Apollo group, and originally a Virtual Impactor (VI). It was first observed on 27 February 2023, when it was 0.11 AU (16 million km) from Earth, with the Isaac Newton Telescope by Ovidiu Vaduvescu, Freya Barwell, and Kiran Jhass (ING and University of Sheffield student support astronomers) within ...
It brightened to apmag 15.3 on 2023-Apr-24. ^ Mercury also will pass 260.9 LD from Earth on January 8, 244.4 LD from Earth on September 3, and 263.2 LD from Earth on December 23. Mercury makes a closest approach to Earth about every 116 days. ^ The asteroid with the greatest chance of impacting Earth in 2023 is 2016 LP10 (4-meters in diameter ...
2023 DW is a near-Earth asteroid of the Aten group.It is approximately 50 meters (160 feet) in diameter, roughly the size of the asteroid that caused the Tunguska event, [a] and was discovered by Georges Attard and Alain Maury, from the MAP (Maury/Attard/Parrott) asteroid search program in San Pedro de Atacama on 26 February 2023, when it was 0.07 AU (10 million km) from Earth.

The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
This diagram made available by NASA shows the estimated trajectory of asteroid 2023 BU, in red, affected by the earth's gravity, and the orbit of geosynchronous satellites, in green.
2023 NT1 is a near-Earth asteroid, approximately 30 meters in diameter, [1] that passed within 1/4 lunar distances on July 13, 2023. It was not discovered until 2 days after closest approach due to coming from the daylight direction. [2] [3]
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. 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.
List of Mercury-crossing minor planets. A Mercury crosser or Mercury grazer is an asteroid whose orbit crosses that of Mercury. The Mercury crossers proper have aphelia outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU), whereas those listed here as outer grazers have perihelia within Mercury's aphelion but not within its ...
