207945

207945 is an asteroid designated as 2003 YT1, discovered on December 16, 2003, by astronomers at the Apache Point Observatory in New Mexico as part of the Sloan Digital Sky Survey. It is classified as a near-Earth object (NEO) and a potentially hazardous asteroid (PHA) due to its orbit, which brings it relatively close to Earth’s trajectory.

The asteroid has an estimated diameter of approximately 0.4 kilometers (0.25 miles), placing it among the larger objects in the PHA category. Its orbit around the Sun takes about 1.5 years, and it occasionally approaches Earth within roughly 0.05 astronomical units (AU), or about 7.5 million kilometers (4.6 million miles). While this distance is considered safe by astronomical standards, its size and proximity warrant ongoing monitoring by space agencies and observatories.

207945 is part of the Apollo group of asteroids, which are known for their Earth-crossing orbits. Its trajectory has been studied extensively to assess any potential future risks, though current calculations indicate no significant threat of impact with Earth in the foreseeable future. NASA and other organizations continue to track its movement as part of broader efforts to identify and characterize NEOs.

The asteroid’s designation reflects its discovery date and sequence within the year, with "2003" indicating the year of observation and "YT1" representing its provisional naming convention. Over time, it may receive a permanent number and a name if further observations confirm its orbit and characteristics.
