More recently, space observatories found that Eta Carinae creates strong X-ray outbursts every 5½ years.

Preview of a Forthcoming Supernova. Eta Carinae is approximately 7,500 light years from Earth. Eta Carinae's two stars orbit their common center of mass every 5½ years.


The HST resolves individual clumps as small as only about ten times the size of our Solar System. Eta Carinae is located in the direction of Carina constellation. NGC 3372 is exceptionally large, about four times the size of the Orion Nebula ().It can easily be seen without binoculars even though it is about five times more distant than the famous nebula in Orion constellation.. Eta Carinae Nebula is not quite as well known as the Orion Nebula because it lies in the southern sky and can only be observed from equatorial and southern latitudes. Distance, Size, and Mass. A Hubble Space Telescope observation of the star Eta Carinae, made with the Wide Field and Planetary Camera (WF/PC). 02.24.12 › Larger image At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. A new study using data from NASA's NuSTAR space telescope suggests that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is accelerating particles to high energies - some of which may reach our planet as cosmic rays.

Eta Carinae (η Carinae, abbreviated to η Car), formerly known as Eta Argus, is a stellar system containing at least two stars with a combined luminosity greater than five million times that of the Sun, located around 7,500 light-years (2,300 parsecs) distant in the constellation Carina.

NASA / Goddard Space Flight Center. Fortunately, the answer is no. The Eta Carinae is located at around 7.500 light-years / 2.300 parsecs away from the Sun. Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still don't understand.

Eta Carinae (η Carinae or η Car) is a superbright hypergiant star in the constellation Carina, about 7,500 to 8,000 light-years from the Sun.. It then slowly faded until, in 1868, it became invisible in the sky.

A hot supergiant of about 30 solar masses is in orbit around the primary. It is one of a small class of stars called luminous blue variables. Eta Carinae’s most recent outburst in 1841 expelled the gas that creates the spectacular nebula (sometimes called the Homunculus Nebula) that we see today. Eta Carinae, also called Homunculus Nebula, peculiar red star and nebula about 7,500 light-years from Earth in the southern constellation Carina and now known to be a binary star system. Text Size. It has brightened and faded over the years, and some astronomers think it could explode as a supernova in the not-too-distant future. Eta Carinae is 7,500 light-years away in the constellation Carina. When closest, they're only about 225 million km (140 million miles) apart. It is around 100 times the mass of our sun and is burning its nuclear fuel so quickly that it is at least one million times brighter than the sun.
