What is the largest desert in the world?

The largest desert in the world is the Antarctic Desert, also known as the Polar Desert or the South Polar Desert. It covers the continent of Antarctica and has an area of about 14 million square kilometers (5.4 million square miles). The Antarctic Desert is considered a cold desert because it has very little precipitation and extremely low temperatures.

Despite its harsh conditions, the Antarctic Desert is home to a variety of wildlife, including penguins, seals, and birds. It is also an important research site for scientists studying climate change and the Earth's atmosphere.
