'''(17246) 2000 GL74''' is a [[Main belt]] [[asteroid]]. It was discovered by the [[LINEAR]] program on April 5, 2000. It is known to possess a [[Asteroid moon|moon]]: S/2004 (17246) 1.

== Characteristics ==
(17246) 2000 GL74 is more reflective than most asteroids, with an albedo of 0.21. Even so, it is not very bright, having a size of only 4.5 [[kilometres]].<ref name= "Johnston archive" /> Its rotation period of 10 [[hours]] is not unusual, however.

=== Close Approaches ===
[[File:Juno mpl anim.gif|thumb|left|3 Juno, the asteroid that (17246) GL74 will approach on January 9, 2129]]
On January 9, 2129, (17426) 2000 GL74 will come within 3,639,998 kilometres of the asteroid [[3 Juno]]. It will pass it with a relative velocity of 6.597 km/s.<ref name= "JPL SBDB" />

== Moon ==
(17246) 2000 GL74 has one moon, S/2004 (17246) 1. It is 44% the size of (17246) 2000 GL74, at 2 km.<ref name= "Johnston archive" /> While its rotation period and orbital eccentricity is not yet known, it is known that the moon completes one orbit every 90 days at a distance of about 250 km. From the surface of (17246) 2000 GL74, S/2004 (17246) 1 would have an apparent diameter of about 0.668°, slightly larger than the [[Moon]] appears from [[Earth]].<ref group="lower-alpha">Calculated by solving <math> \scriptstyle{\mathrm{tan}\left(\frac{\theta}{2}\right) = \frac{\mathrm{radius~of~moon}}{\mathrm{distance~from~surface~of~asteroid~to~center~of~moon}}}</math>.</ref>
