'''273 Atropos''' is a typical [[Asteroid belt|Main belt]] [[asteroid]] that was discovered by Austrian astronomer [[Johann Palisa]] on 8 March 1888 in [[Vienna]].

[[Photometry (astronomy)|Photometric]] observations of this asteroid at the Palmer Divide Observatory in [[Colorado Springs, Colorado]], in 2007 gave a [[light curve]] with a period of 23.852 ± 0.003 hours and a brightness variation of 0.60 ± 0.03 in [[Magnitude (astronomy)|magnitude]].<ref name="Warner2007"/>
