    (237442) 1999 TA10, provisionally known as 1999 TA10, is a near-Earth object (NEO) from the Amor asteroid group. [2] It is suspected of being an inner fragment of the differentiated asteroid 4 Vesta. [4]

    Given an absolute magnitude (H) of 17.9, [2] and that the albedo is unknown, this NEO could vary from 500 to 1500 meters in diameter. [3]

    1999 TA10 was discovered by LINEAR at Lincoln Laboratory ETS on 5 October 1999 at apparent magnitude 17.7, [1] when it was only 0.39  AU from Earth. [5] In 2010, it came within 0.3 AU of Earth. [5] During the 2010 close approach, NASA Infrared Telescope Facility (NASA IRTF) studies suggested that 1999 TA10 originated from the interior of Vesta. [4] The next close approach will be in 2023. [5] In 2086, it will come within 0.017  AU (2,500,000  km ; 1,600,000  mi ) of Mars. [5]

    (276033) 2002 AJ129, provisional designation 2002 AJ129, is a Mercury-crossing asteroid. It has the ninth-smallest perihelion of all numbered asteroids, after asteroids such as 2000 BD19, 2004 UL, and 2008 XM. It makes close approaches to all of the inner planets and asteroid 4 Vesta. The asteroid is estimated to be between 0.5–1.2 kilometers (0.3–0.7 mi) across. In January 2018 there was much media hype about this asteroid being classified as a potentially hazardous asteroid, although there is no known threat of an impact for hundreds if not thousands of years. The media has compared the size of the asteroid to the Burj Khalifa in Dubai.

    (511002) 2013 MZ5, provisional designation 2013 MZ5, is a sub-kilometer asteroid, classified as a near-Earth object of the Amor group, estimated to measure approximately 300 meters (1,000 feet) in diameter. It was discovered on 18 June 2013, by astronomers with the Pan-STARRS survey at Haleakala Observatory on the island of Maui, Hawaii, in the United States. It was the 10,000th near-Earth object ever discovered.

    2014 EC is a 10-meter sized, eccentric asteroid, classified as near-Earth object of the Apollo group that passed within 48,000 miles (77,000 km) of Earth in early March 2014. This was six times closer to the Earth than the Moon. It was first observed on 5 March 2014, by the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States. As of 2017, it has not since been observed.

    2010 XG11 is an Amor near-Earth asteroid. It was discovered on 5 December 2010 by the Catalina Sky Survey at an apparent magnitude of 19.7 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope. Three precovery images are known from 1 July 1995. With an observation arc of 16 years, the orbit is well determined with an orbital uncertainty of 0. With an absolute magnitude of 20.0, the asteroid is about 270–590 meters in diameter.

    2014 SC324 is a sub-kilometer asteroid and fast rotator, classified as a near-Earth object of the Apollo group, approximately 50 meters in diameter. It was first observed on 30 September 2014, by the Mount Lemmon Survey at an apparent magnitude of 21 using a 1.5-meter (59 in) reflecting telescope. With an absolute magnitude of 24.3, the asteroid is about 37–85 meters in diameter.

    2014 OO6 (also written 2014 OO6) is an Apollo near-Earth asteroid discovered in 2014 and was the most dangerous one discovered in 2014 that remained on the Sentry Risk Table as of early December 2014. The asteroid is estimated to be roughly 75 meters (246 ft) in diameter and had a 1 in 83,000 chance of impacting Earth on 11 January 2051. However, the nominal best-fit orbit shows that 2014 OO6 will be 1.5 AU (220,000,000 km; 140,000,000 mi) from Earth on 11 January 2051.

    2014 XL7 is a near-Earth object and Apollo asteroid, approximately 230 meters (750 feet) in diameter. It was the most dangerous potentially hazardous asteroid on Sentry Risk Table upon its discovery by the Mount Lemmon Survey in December 2014. At the time, the asteroid had a cumulative 1 in 83000 chance of impacting Earth on 4–5 June between the years 2048 and 2084. After the object's observation arc had been extended to 35 days, it was removed from the Sentry Risk Table on 15 January 2015. Since then the asteroid's orbit has been secured. Although it has an Earth minimum orbit intersection distance of less than one lunar distance, there are no projected close encounters with Earth in the foreseeable future, with its closest passage to occur in May 2046, still millions of kilometers away.

    2015 BP513 (also written 2015 BP513) is an Apollo near-Earth asteroid roughly 12–27 meters in diameter that passed less than 1 lunar distance from Earth on 18 January 2015.

    2015 AZ43 (also written 2015 AZ43) is an Apollo near-Earth asteroid roughly 70 meters in diameter. On 10 February 2015 with a 29.5-day observation arc, it showed a 1 in 5,880 chance of impacting Earth on 27 February 2107. However, the NEODyS nominal best-fit orbit shows that 2015 AZ43 will be 2.8 AU (420,000,000 km; 260,000,000 mi) from Earth on 27 February 2107. A (non-impacting) Earth close approach in 2056 makes future trajectories diverge. It was removed from the JPL Sentry Risk Table on 23 February 2015 using JPL solution 26 with an observation arc of 40 days that included radar data.
