NGC 7686 is a moderately-sized open cluster in the constellation Andromeda, containing about 80 stars. [2] At magnitude 5.6, it is an easy target for binoculars and small telescopes. [3] According to Johnson et al. (1961), the "color-magnitude diagram shows merely a uniform scatter with no significant tendency to show a cluster main sequence ...
a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
51 Andromedae, abbreviated 51 And and formally named Nembus / ˈ n ɛ m b ə s /, [8] is the 5th brightest star in the northern constellation of Andromeda, very slightly dimmer than the Andromeda Galaxy also being of 4th magnitude.
A visual band light curve for Zeta Andromedae, adapted from Kővári et al. (2006) [8]. The system is a spectroscopic binary whose primary is classified as an orange K-type giant with a mean apparent magnitude of +4.08.
Andromeda I is part of the local group of galaxies and a satellite galaxy of the Andromeda Galaxy (M31). It is roughly 3.5 degrees south and slightly east of M31. [ 6 ] As of 2005, it is the closest known dSph companion to M31 [ 7 ] at an estimated projected distance of ~40 [ 4 ] kpc or ~150,000 [ 6 ] light-years.
Constellation Energy stock fell 12.5% Monday amid a broader decline in nuclear power stocks following the US government's rejection of another Big Tech nuclear power agreement late Friday.
The object has an apparent visual magnitude of 8.3 and spans an angular size of 32″ × 28″. [2] Parallax measurements give a distance estimate of 5,730 ± 340 ly (1,757 ± 103 pc). [1] NGC 7662 is a popular planetary nebula for casual observers. A small telescope will reveal a star-like object with slight nebulosity.
The possible exoplanet would have a mass of 6.34 Jupiter mass.If confirmed, it would be the first exoplanet found in another galaxy. [4] A similar event was seen in 1996 when a team of astronomers discovered an anomalous fluctuation in the Twin Quasar's lightcurve that seemed to be caused by a planet approximately three Earth masses in size in the quasar's lensing galaxy YGKOW G1.
