h Persei and χ Persei (2024)

FAQs

How old is H and Chi Persei? ›

NGC 869 (also known as h Persei) is an open cluster located 7460 light years away in the constellation of Perseus. The cluster is about 14 million years old. It is the westernmost of the Double Cluster with NGC 884. NGC 869 and 884 are often designated h and χ (chi) Persei, respectively.

Given its visual magnitude of 3.7, NGC 869 is barely visible to the naked eye, easily visible with the help of a small binocular.

The Double Cluster is circumpolar (continuously above the horizon) from most northern temperate latitudes. It is in proximity to the constellation Cassiopeia. This northern location renders this object invisible from locations south of about 30º south latitude, such as New Zealand, most of Australia and South Africa.

Visible to the naked eye from a dark location, Caldwell 14 is popularly known as the Double Cluster in Perseus. These two bright open clusters, also called NGC 869 and NGC 884, appear side by side, about halfway between the bright stars in the constellations Perseus and Cassiopeia.

The star sigma Orionis is 3 million years old and has a high temperature: its surface temperature is 30,000K five times hotter than that of the Sun. This very high temperature makes the star have a blueish colour, in contrast to less massive stars which have reddish colours.

Omicron Persei – About 1,100 light-years away from us, this star in the constellation Perseus is not one, but two. The bright main star – traditionally called Atik for “the shoulder” in Arabic – has a small companion. That companion is so close that a single orbit takes less than 5 days.

Xi Persei has an apparent magnitude of +4.06 and is classified as a blue giant (spectral class O7.

Zeta Persei (ζ Per, ζ Persei) is a star in the northern constellation of Perseus. With an apparent visual magnitude of 2.9, it can be readily seen with the naked eye. Parallax measurements place it at a distance of about 750 light-years (230 parsecs) from Earth.

Because the constellation is in a circumpolar position (meaning that it seems to revolve centered around the pole star, Polaris), Cassiopeia is at times suspended upside down in the sky in a very undignified position.

Is Cassiopeia The Little Dipper? ›

Cassiopeia is opposite the Big Dipper in the northern sky. That is, the two constellations lie on opposite sides of the pole star, Polaris. So when Cassiopeia is high in the sky, as it is on evenings from about September through February, the Big Dipper is low in the sky.

Appearance. Cassiopeia is a slim woman who wears only a Shuriman headdress, bra and armbands on her elbows. After being transformed by her curse, her legs turned into a long green snake tail merged into her body with a golden belt, and her fingers have become golden with an adorned jewel on the back of each hand.

The cluster contains 190 galaxies including NGC 1275 which sits near the centre of this image, and is part of the Pisces-Perseus supercluster, which contains over 1000 galaxies.

The Pleiades are an open star cluster, which is when a group of stars are born at a similar time from a gigantic cloud of gas and dust. As they're made from the same material, this makes the Pleiades a stellar family.

Emmett (Jacob Latimore) starts Season 1 as a charismatic 16-year-old sneakerhead. His father is involved in a gang, and his mother is an addict.

This is a young star with an age of only three million years. Its luminosity is varying in a periodic manner similar to that of a Beta Cephei variable.
