Which astronomical object is located within a stellar system at a distance of 7500-8000 light years?

Eta Carinae is a highly notable star system located approximately 7500-8000 light years away from Earth. It is known for being one of the most massive binary systems in our galaxy and has a fascinating history, including dramatic outbursts and changes in brightness. The system contains two massive stars that are thought to have a significant impact on their surrounding environment due to their high luminosity and stellar winds.

In contrast, the other objects listed have different characteristics and locations. The Vela Supernova Remnant is the remnant of a supernova explosion located around 800 light years away, significantly closer than Eta Carinae. NGC 1846 is a loose star cluster situated in the Large Magellanic Cloud, farther away than both the Vela Supernova Remnant and Eta Carinae. The Andromeda Galaxy, as a neighboring spiral galaxy, is located about 2.537 million light years from Earth, placing it far beyond the 7500-8000 light year range.

Understanding the distances and nature of these astronomical objects helps in comprehending the structure of our galaxy and the different types of celestial phenomena that can be observed.
