[Note 1] [7] Thus, a body of magnitude 1 is 2.512 5 (~100) times brighter than a body of magnitude 6. [8] The dimmest stars that can be seen through a 200-inch terrestrial telescope are of the 20th magnitude, and very bright objects like the Sun and a full Moon have magnitudes of −26.7 and −12.6 respectively.
In 2018 Polaris was 0.66° (39.6 arcminutes) away from the pole of rotation (1.4 times the Moon disc) and so revolves around the pole in a small circle 1.3° in diameter. It will be closest to the pole (about 0.45 degree, or 27 arcminutes) soon after the year 2100. [ 34 ]
Sigma Octantis is the closest near naked-eye star to the south celestial pole, but at apparent magnitude 5.47 it is barely visible on a clear night, making it less useful for casual navigational or astronomy alignment purposes. [14] [15] It is a yellow giant 294 light years from Earth. Its angular separation from the pole is about 1° (as of 2000).
The second mission in the Polaris Program will launch via a Falcon 9 Block 5 vehicle with a Crew Dragon capsule. SpaceX and Polaris had studied a crewed mission to lift the Hubble Space Telescope into a higher orbit to prevent it from burning up in the atmosphere, [4] [5] but this option was rejected by NASA in June 2024.

Little Cornwallis Island was the home to Polaris Mine, the most poleward base-metal mine in the world. In 1960 a vast concentration of zinc and lead was discovered on the island during mapping for oil permits. Cominco acquired land in the area and a gravity survey in 1970 detected a large anomaly. By 1973 surface drilling and underground ...

[2] Polaris lies in the Grasshopper Valley, along the Pioneer Mountain Scenic Byway, southeast of Wisdom. This community takes its name from the Polaris Mine, which operated as a silver mine from 1885 until ...
Polaris zinc mine was a former underground mine on Little Cornwallis Island in the Canadian territory of Nunavut (Northwest Territories prior to Nunavut's official separation). [2] The zinc mine was located 1,120 km (700 mi) north of the Arctic Circle , and 96 km (60 mi) north of the community of Resolute . [ 3 ]
