Ontario Lacus is a lake composed of methane, ethane and propane near the south pole of Saturn‘s moon Titan. Its character as a hydrocarbon lake was confirmed by observations from the Cassini spacecraft, published in the 31 July 2008 edition of Nature. Ontario Lacus has a surface area of about 15,000 square kilometers (5,800 sq mi), about 20% smaller than its terrestrial namesake, Lake Ontario in North America. In April 2012, it was announced that it may be more like a mudflat or salt pan.
Any waves present on the lake are also far smaller than those that would be present on a sizable body of liquid water on Earth; their estimated maximum height was less than 3 mm during observations of a radar specular reflection during Cassini’s T49 flyover of July 2009. On Titan, waves can be generated at lower wind speeds than on Earth, due to the four times greater atmospheric density, and should be seven times higher at a given wind speed, due to Titan’s surface gravity being one seventh as strong. The lack of waves could indicate either wind speed less than 0.5 m/s, or an unexpectedly viscous composition of the hydrocarbon fluid. However, the apparent presence of a wave-generated beach on the lake’s northeast shore suggests that at times considerably higher waves form.
