Ar-Rubʿ al-Khālī (the "Empty Quarter") is the largest continuous sand desert in the world on the Arabian Peninsula. It is a hyper‑arid region of vast sand seas (ergs), with high sand dunes, interdune plains, occasional salt flats (sabkhas) and almost no permanent surface water or settlements.

Three facts
1. Size: It covers roughly 650,000 km² (about 250,000 sq mi), making it one of the largest sand deserts on Earth.
2. Dunes and landscape: The desert is dominated by mega-ridge and star dunes that can reach heights of around 200–250 m (650–820 ft).
3. Climate and habitability: It is hyper‑arid — annual rainfall is extremely low (often under a few tens of millimetres per year) — and is largely uninhabited, though nomadic groups and modern exploration teams have crossed it.

Location
Ar-Rubʿ al-Khālī lies in the southern part of the Arabian Peninsula. It extends across southeastern Saudi Arabia and into southern Oman, the eastern part of Yemen, and the southwestern United Arab Emirates. It occupies a central-southern belt of the peninsula and forms a major part of the Arabian Desert landscape.
