All three of these are blue-white giant stars. The brightest of these is Men with a visual magnitude of 2. It is ten times more massive than the Sun and is 25, times brighter. It is located about light years from Earth. Kekouan is the second brightest star with a magnitude of 2. It lies approximately light years away.
Gamma Lupi is the third brightest star with a magnitude of 2. It lies some light years from our solar system. Lupus contains no Messier objects but it does contain a few notable deep-sky objects. NGC is a globular star cluster that contains thousands of individual stars.
It is located approximately 33, light years from Earth. It is a close binary system where the primary component is a spectroscopic binary star. It has an orbital period of 2. Gamma Lupi is located approximately light years away from the Solar System. Delta Lupi is a blue-white subgiant with the stellar classification B1. It is a Beta Cephei variable with a period of 0. The star is located around light years away from the Sun and is around 15 million years old.
It has a mass that is 12 times that of the Sun and a radius that is 6. It is also around 10, times more luminous than the Sun. Epsilon Lupi has a visual magnitude of 3. It is a multiple star system that is a double-lined spectroscopic binary. The stars share a close orbit with a period of 4. There is also a companion to the binary system that is separated by Zeta Lupi is a yellow giant star that belongs to the stellar class G7III and has an apparent magnitude of 3.
It is located around light years away from the Sun. Eta Lupi is a blue-white subgiant that belongs to the stellar class B2. It is located around light years away from the Solar System. Iota Lupi is a class B subgiant that has the stellar classification of B2. It is located around light years away from Earth. Phi-2 Lupi is a blue-white main sequence star with the stellar classification of B4V and an apparent magnitude of 4.
Pi Lupi is a double system star that belongs to the spectral class B5. It has an apparent magnitude of 3. Tau-1 Lupi is a blue-white subgiant star that belongs to the stellar class B2IV and has an apparent magnitude of 4. It is also a Beta Cephei variable star and is located around 1, light years away from us. Tau-2 Lupi is a F7-class star with a visual magnitude of 4. It is located about light years away from Earth. Nu-1 Lupi is a yellow-white star, halfway between the subgiant and giant evolutionary stage, with the stellar classification of F6III-IV and an apparent magnitude of 5.
Nu-2 Lupi is a yellow main sequence star with which is very similar to the Sun but with a significantly lower metallicity. It has a mass that is 1. It is also 0. In September , three planets were discovered orbiting Nu-2 Lupi. KT Lupi, also known as G. Lupi, is blue-white subgiant star with the stellar classification of B3IVp and an apparent magnitude of 4. It is a Be star, meaning that it is a class B star with strong hydrogen emission lines and distinctive forbidden neutral or low ionization emission lines in its spectrum.
It is around light years away from Earth. GQ Lupi is an orange main sequence star which is classified as a T Tauri variable and has an apparent magnitude of It is located around light years away from Earth and is less than 2 million years old. Ru Lupi is a yellow star with the stellar classification of G5V:e and an apparent magnitude of It is also a T Tauri variable and is very young, between 2 and 3 million years old. RU Lupi exhibits random variations in brightness, including fluctuations in ultraviolet and X-ray emissions, and is surrounded by a circumstellar disk of dust.
It also has an unconfirmed substellar companion in its orbit. It is located around 1, light years away from us. SN is a historic supernova, seen between April 30 and May 1 of the year It is believed to have been a Type Ia supernova and it reached a visual magnitude of In a low power eyepiece, this star cluster will look like a just a loose group of stars which almost blend with the background star field. Containing around 35 members with the brightest about magnitude 10, keep to lower magnification to keep the target in site!
Lupus is part of this area whose perimeter contains star forming regions which came to life about 30 million years ago when a huge molecular cloud of dust and gas was compressed — much like in the Orion area. Locate Theta Lupi and head around five degrees west for NGC RA 15 46 03 Dec 37 47 10 , a 7th magnitude globular cluster which can be spotted with binoculars with good conditions. While this Class VII cluster is not particularly dense, many of its individual stars can be resolved in a small telescope.
This is dark nebula B — a cloud of dark, obscuring dust which blocks incoming starlight. Eta is a fine double star which can even be resolved with binoculars.
When you are done, hop another roughly five degrees southeast RA 16 25 18 Dec 40 39 00 to encounter the fine open cluster NGC Discovered by Lacaille and known to him as object I. Situated about 19 light-years away, it will show as a fine, round, faint spray of stars to binoculars and be resolved into about stellar members to larger telescopes.
