The Sahara is the world's largest hot desert, and second largest desert after Antarctica at over 9,000,000 km² (3,500,000 mi²), almost as large as the United States. The Sahara is located in Northern Africa and is 2.5 million years old.
The name Sahara is an English pronunciation of the Arabic word for desert, صحراء (help·info)).

Just in case you or anybody else besides these brainiacs thinks a desert is just sand.
In geography, a desert is a landscape form or region that receives very little precipitation. Generally, deserts are defined as areas that receive an average annual precipitation of less than 250 mm (10 inches). The terminology used to define deserts is complex. 'True deserts' where vegetation cover is exceedingly sparse, correspond to the 'hyperarid' regions of the earth, where rainfall is exceedingly rare and infrequent. Deserts are however part of a wider classification of regions that, on an average annual basis, have a moisture deficit (i.e. they can potentially lose more than is received). These areas are collectively called 'drylands' and extend over almost half of the earth's land surface. Because desert is a vague term, the use of 'dryland', and its subdivisions of hyper arid, arid, semiarid and dry-subhumid, is to be preferred, and is approved by the United Nations.
Deserts cover at least one-fourth of the Earth's land surface. Deserts are very arid (dry) and can have high temperatures in excess of 50°C (122 F). Even though the desert is often very hot in the day, it can be extremely cold by night. Deserts have quite rough terrain, many sand dunes and present an overwhelmingly hostile environment. Humans who travel into deserts unprepared have a slim chance of survival due to the relative dearth of water.
Deserts have a reputation for supporting very little life, but in reality deserts often have high biodiversity, including animals that remain hidden during daylight hours to control body temperature or to limit moisture needs.

The largest (nonpolar) desert in the world is the Sahara, in north Africa, which spans an area measured at roughly 3.5 million square miles.
The United States' contiguous 48 states could easily fit in the desert.
It spans more than 3,000 miles across Africa, stretching from the Atlantic Ocean to the Red Sea. It is bordered by the Mediterranean Sea on the north and it spreads all the way down to central Africa, some 1,200 miles south.

the largest desert in the world is Anarctica. The whole continent is a desert as it is so cold that the little water it recieves freezes whenever it comes.

The Sahara Desert in northern Africa. 3.5 million square miles. The entire US could fit inside the Sahara.
