NGC 188 (also known as Caldwell 1 or the Polarissima Cluster[5]) is an open cluster in the constellation Cepheus. It was discovered by John Herschel in 1825.

Aug 23, 2024 · An image in the lower left, taken with the 0.9-meter telescope at Arizona’s Kitt Peak National Observatory, provides a full view of star cluster Caldwell 1 (NGC 188). The inset shows Hubble’s Wide Field Camera 3 (WFC3) close …

May 12, 2009 · We present time series radial velocity, and photometric observations of a solar-type double-lined eclipsing binary star (V 12) in the old open cluster NGC 188. We use these data to determine the spectroscopic orbit and the photometric elements for V 12.

Nov 21, 2023 · NGC 188 has the dual distinction of being both the northernmost and the oldest open star cluster visible from Earth. M78 is a bright reflection nebula located close to the celestial equator, and about four degrees east of Mintaka (Delta Orionis), the …

NGC 188 is a Open Cluster in the Cepheus constellation. NGC 188 is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere. Given its visual magnitude of 8.1, NGC 188 is visible with the help of a binocular with a 40-50mm aperture or a small telescope.

The open cluster NGC 1888 can be found in the constellation Cepheus, circa 4° away from the pole star and hence visible all year long in Europe. Charts created using SkySafari 6 Pro and STScI Digitized Sky Survey.

Dec 9, 2020 · Discovered in 1825, NGC 188 is an open cluster in the constellation Cepheus, located some 5,400 light years away from the Earth. It has a solar metallicity, a radius of about 11.8 light years,...

NGC 188 is less than 5 degrees from the north celestial pole, so it is visible every clear night of the year for northern hemisphere observers. The cluster is quite faint, with its stars ranging from about magnitude 12 to 15, so it is not a dazzling object through a telescope.

Sep 13, 2022 · The orbit parameters indicate that NGC 188 is a typical thick-disk cluster located well outside the solar circle. This paper revisits fundamental properties of the old open cluster NGC 188 based on more reliable cluster members in $Gaia$ -EDR3.

Caldwell 1 (NGC 188) is a open cluster located within the constellation Cepheus. C1 is best viewed during Fall, is magnitude 8.1*, and can be viewed with binoculars. It is 14' in size. For reference, the full moon is 30' (arc minutes) in size.
