Polaris Aa, the supergiant primary component, is a low-amplitude Population I classical Cepheid variable, although it was once thought to be a type II Cepheid due to its high galactic latitude. Cepheids constitute an important standard candle for determining distance, so Polaris, as the closest such star, [11] is heavily studied.
σ Octantis (Latinised to Sigma Octantis) is the star's Bayer designation. As the southern hemisphere's pole star it bore the name Polaris Australis, first applied in the 1700s. [12] In 2016, the IAU organized a Working Group on Star Names (WGSN) [13] to catalog and standardize proper names for stars. The WGSN approved the name Polaris ...
Northern Hemisphere circumpolar stars around Polaris, with a long-exposure producing a star trail photo. A pole star is a visible star that is approximately aligned with the axis of rotation of an astronomical body; that is, a star whose apparent position is close to one of the celestial poles. On Earth, a pole star would lie directly overhead ...
The star Polaris, often called either the "Pole Star" or the "North Star", is treated specially due to its proximity to the north celestial pole. When navigating in the Northern Hemisphere , a simple and quick technique can be used with Polaris to determine the observers latitude or, for larger maritime vessels can be used to calculate any ...
The north celestial pole currently is within one degree of the bright star Polaris (named from the Latin stella polaris, meaning "pole star"). This makes Polaris, colloquially known as the "North Star", useful for navigation in the Northern Hemisphere: not only is it always above the north point of the horizon, but its altitude angle is always ...
Vega. Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years (7.7 parsecs) from the Sun, and one of the most luminous stars in the Sun's neighborhood.
A star chart of the entire Northern Sky, centered on the north celestial pole. The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.
The four members of the Polaris Dawn crew marvel at the Falcon 9 rocket that will soon take them into orbit aboard a SpaceX Dragon. The objectives for the crew's five-day stay aboard a SpaceX Crew ...
