NGC 7006 (also known as Caldwell 42) is a globular cluster [2] in the constellation Delphinus. NGC 7006 resides in the outskirts of the Milky Way. It is about 135,000 [6] light-years away, five times the distance between the Sun and the centre of the galaxy, and it is part of the galactic halo.

NGC 7006，也稱為 科德韋爾42，是位於 海豚座 的一個 球狀星團 [1]。

2024年8月23日 · Caldwell 42, also known as NGC 7006, is one of 18 globular clusters in the Caldwell catalog. If you look at this Hubble image of the cluster closely, you may be able to spot several tiny background galaxies (which appear fuzzier and more extended than the …

2023年8月14日 · NGC 7006 is a compact and distant globular star cluster that lies in one of the smallest constellations in the night sky, Delphinus (The Dolphin). NGC 7006 resides in the outskirts of the Milky Way. It is about 135,000 light-years away, five times the distance between the Sun and the centre of the galaxy, and it is part of the galactic halo.

2011年9月12日 · NGC 7006 resides in the outskirts of the Milky Way. It is about 135 000 light-years away, five times the distance between the Sun and the centre of the galaxy, and it is part of the galactic halo. This roughly spherical region of the Milky Way is made up of dark matter, gas and sparsely distributed stellar clusters.

NGC 7006 is a Globular Cluster in the Delphinus constellation. NGC 7006 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

2023年8月7日 · Like other remote globular clusters, NGC 7006 provides important clues that help astronomers to understand how stars formed and assembled in the halo. The cluster has a very eccentric orbit, indicating that it may have formed independently in a small galaxy outside our own that was then captured by the Milky Way.

Although relatively small and faint (Mv 10.6), NGC 7006 is very dense as a class 1 globular. This is one of the farthest globular clusters within easy reach of amateur telescopes; 135,000 light years from us and 127,000 light years from the galactic center.

NGC 7006 appears to be about 150,000 light years from the center of our Galaxy and some 185,000 light years from the Solar System. This is almost comparable to the distances of the Magellanic Clouds and suggests that these two clusters might possibly be regarded as extra-galactic objects.
