Lake Titicaca

Titicaca (in the hispanicized spelling) or Titiqaqa (Quechua) is a large, deep lake in the Andes on the border of Peru and Bolivia. By volume of water, it is the largest lake in South America.Lake Maracaibo has a larger surface area, though some consider it to be a large brackish bay due to its direct connection with the sea.

It is often called the highest navigable lake in the world, with a surface elevation of 3,812 metres (12,507 ft). Although this refers to navigation by large boats, it is generally considered to mean commercial craft. For many years the largest vessel afloat on the lake was the 2,200-ton, 79-metre (259 ft) SS Ollanta. Today the largest vessel is probably the similarly sized, but broader, train barge/float Manco Capac, operated by PeruRail (berthed, as of 17 June 2013, at 15°50′11″S 70°00′53″W / 15.8364°S 70.0147°W / -15.8364; -70.0147, across the pier from the Ollanta). At least two dozen bodies of water around the world are at higher elevations, but all are much smaller and shallower.

1801 Titicaca

1801 Titicaca, provisional designation 1952 SP₁, is a stony asteroid from the asteroid belt, about 23 kilometers in diameter. It was discovered by Argentine astronomer Miguel Itzigsohn at La Plata Observatory in the capital of the province of Buenos Aires on 23 September 1952.

The S-type asteroid orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,917 days). With a semi-major axis of 3.02 AU, an eccentricity of 0.07 and an inclination of 11 degrees, the body is a typical member of the Eos family of asteroids.

It has a rotation period of 3.2 hours and a geometric albedo between 0.12 and 0.17 based on observations of the WISE/NEOWISE missions and derived calculations by the LCDB project, respectively.

The asteroid is named after Lake Titicaca in the Andes, on the border of Peru and Bolivia at an altitude of 3,812 metres (12,507 feet) above sea level, the largest lake by volume in South America and one of the largest and highest lakes in the world.
