[3] The second deepest is the Dragon Hole, or Longdong, in the South China Sea at 300.89 metres (987 ft) deep, [4] while the third deepest blue hole in the world is Dean's Blue Hole at 202 metres (663 ft) , located in a bay west of Clarence Town on Long Island, Bahamas. Other blue holes are about half that depth at around 100–120 metres (330 ...
Known as Dean’s Blue Hole, this geological wonder located off the coast of Long Island is a staggering 663 feet deep, making it one of the deepest blue holes in the world and also an area ripe ...

The origins of the flag's design date from the First Zionist Congress in 1897; the flag has subsequently been known as the "flag of Zion".
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
The horizontal, or altitude-azimuth, system is based on the position of the observer on Earth, which revolves around its own axis once per sidereal day (23 hours, 56 minutes and 4.091 seconds) in relation to the star background. The positioning of a celestial object by the horizontal system varies with time, but is a useful coordinate system ...
Dubhe and Merak (Alpha and Beta Ursae Majoris), the two stars at the end of the bowl of the Big Dipper are often called the Pointers: [18] a line from β to α and continued for about five times the distance between them arrives at the North Celestial Pole and the star Polaris (α UMi/Alpha Ursae Minoris), the North Star.
