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.

NGC 188（也称为Caldwell 1）是在 仙王座 的一个 疏散星团，它于1825年被 约翰·赫歇尔 发现。 不同于其它大多数的疏散星团，由于我们银河系的引力作用，经过数百万年的漂移，NGC 188已经远离了银河平面。 它被认为比银河系中其它的疏散星团更古老，估计其年龄为50亿岁，是最古老的之一。 NGC 188非常靠近银河的北极，距离只有5度，位置在仙王座，与我们相距大约5,000光年，它的位置略高于银河的盘面，并且比太阳系更接近银河的中心。 NGC 188（也称 …

With a 6-inch rich-field telescope, NGC 188 appears as a soft glow, speckled with tiny, often elusive, individual stars. Through a 10-inch or larger aperture the view is spectacular, and the whole field is scattered with diamond dust. Studies indicate that NGC 188 is the most ancient of the known open clusters.

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.

2009年5月12日 · 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.

NGC 188 (also known as Caldwell 1) is an open cluster in the constellation Cepheus about 5000 light-years away. It was discovered by John Herschel in 1831, who cataloged it with the number 34 (h 34). ...

From Virginia Beach , NGC188 is very well placed – it is close enough to the north celestial pole that it is high above the horizon all night. All times shown in Virginia Beach local time.

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.
