Surface features Titania with surface features labeled Among Uranus' moons, Titania is intermediate in brightness between the dark Oberon and Umbriel and the bright Ariel and Miranda .  Its surface shows a strong opposition surge : its reflectivity decreases from 35% at a phase angle of 0° ( geometrical albedo ) to 25% at an angle of about 1°. Titania has a relatively low Bond albedo of about 17%.  Its surface is generally slightly red in color, but less red than that of Oberon .  However, fresh impact deposits are bluer, while the smooth plains situated on the leading hemisphere near Ursula crater and along some grabens are somewhat redder.   There may be an asymmetry between the leading and trailing hemispheres;  the former appears to be redder than the latter by 8%. [h] However, this difference is related to the smooth plains and may be accidental.  The reddening of the surfaces probably results from space weathering caused by bombardment by charged particles and
