This is the Arabian desert . It is commonly referred to as the desert of the Arab Peninsula
It occupies an area of 900,000 square miles. On the south it is bordered by the Gulf of Aden which borders the country of Somalia in Africa and on the northeast, the Arabian desert merges imperceptibly into what is called Arab Asia through the Syrian steppe.
The Arabian desert borders the Nile River Valley on its west and the Gulf of Suez on the eastern end, which makes it essentially surrounded by water on all sides with the exception of the northeast corner that connects it with the Asian continent.
Answer:gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The sun itself rotates slowly, only once a month.

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.
The International Date Line functions as a “line of demarcation” separating two consecutive calendar dates. When you cross the date line, you become a time traveler of sorts! Cross to the west and it’s one day later; cross back and you’ve “gone back in time."
