{{mp|2004 TG|10}}, is an eccentric asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group. First observed by the Spacewatch survey on 8 October 2004, it may be a fragment of Comet Encke and is the source of the Northern Taurids meteor shower seen annually in November{{cite web|url=https://patch.com/us/across-america/taurids-meteor-shower-fireballs-peak-dates-what-expect|title=Taurids Meteor Shower Fireballs: Peak Dates, What To Expect|author=Beth Dalbey|date=24 October 2017|access-date=11 November 2017}} and the June Beta Taurids.Meteor showers and their parent comets [https://books.google.com/books?id=QpajMuyXG8AC&pg=PA470&dq=TG10 pg 470] by Peter Jenniskens The asteroid may be larger than one kilometer in diameter.
Orbit
{{mp|2004 TG|10}} orbits the Sun at a distance of 0.3–4.2 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.86 and an inclination of 4° with respect to the ecliptic.
It has an Earth minimum orbital intersection distance of {{convert |0.0225 |AU |km |abbr=on |sigfig=3}}, which corresponds to 8.8 lunar distances.
Physical characteristics
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 1.316 kilometers in diameter and its surface has an exceptionally low albedo of 0.018, while Porubcan estimates a diameter of 350 to 780 meters, based on an albedo of 0.25 to 0.05, which typically covers most S-type and C-type asteroids.
