Hortensius (Crater)Hortentius is a small, bowl-shaped lunar impact crater that is located in the northern part of the Mare Insularum. It lies some distance to the west-southwest of the prominent Copernicus crater. The crater is circular and cup-shaped, with a small floor at the mid-point of the sloping interior walls. The interior has a higher albedo than the surrounding lunar mare, despite traces of ray material from Copernicus. To the north of this feature is a collection of lunar domes, many having a tiny craterlet at the summit. These are shield volcanoes that were formed by a highly-viscous type of lava. The domes are generally circular in form, with a diameter of 8-12 kilometers, and rising as high as 400 meters. Satellite craters By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Hortensius crater. | idth="25%" style="background:#eeeeee;" |Latitude | width="25%" style="background:#eeeeee;" |Longitude | width="25%" style="background:#eeeeee;" |Diameter | | lign="center"|A | align="center"|4.4° N | align="center"|30.7° W | align="center"|10 km | | lign="center"|B | align="center"|5.3° N | align="center"|29.5° W | align="center"|6 km | | lign="center"|C | align="center"|6.0° N | align="center"|26.7° W | align="center"|7 km | | lign="center"|D | align="center"|5.4° N | align="center"|32.3° W | align="center"|6 km | | lign="center"|E | align="center"|5.2° N | align="center"|25.4° W | align="center"|15 km | | lign="center"|F | align="center"|7.1° N | align="center"|25.6° W | align="center"|6 km | | lign="center"|G | align="center"|8.1° N | align="center"|26.1° W | align="center"|4 km | | lign="center"|H | align="center"|5.9° N | align="center"|31.1° W | align="center"|6 km |
