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.^[2]

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.^[6] 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.^[6] The lack of waves could indicate either wind speed less than 0.5 m/s, or an unexpectedly viscous composition of the hydrocarbon fluid.^[5][6] However, the apparent presence of a wave-generated beach on the lake’s northeast shore suggests that at times considerably higher waves form.^[6]
