2004 PT42 is an asteroid with a period of revolution around the Sun of P=2.9 yr and an orbit quite eccentric (e=0.167) and inclined (i=48.9). Its absolute magnitude (magnitude when the object is 1 au from the Sun and from Earth) is H=16.6 which suggests a size of about 1 km.


The orbit computed from the JPL.

Mid August 2004 it passed near Earth with an apparent velocity of 8 /day and a magnitude of 13. It was observed with a 203 mm SCT and a SBIG ST7E camera.
