Eta Carinae (η Carinae or η Car) is a highly luminous hypergiant star located approximately 7,500 light-years from Earth in the Milky Way galaxy. Since Eta Carinae is 32,000 times closer than SN 2006gy, the light from it will be about a billion-fold brighter. It is estimated to be similar in size to the star which became SN 2006gy. Dave Pooley, one of the discoverers of SN 2006gy, says that if Eta Carinae exploded in a similar fashion, it would be bright enough that one could read by its light on Earth at night, and would even be visible during the daytime. SN 2006gy's apparent magnitude ("m") is 15, so a similar event at Eta Carinae will have an "m" of about −7.5. According to astrophysicist Mario Livio, this could happen at any time, but the risk to life on Earth would be low.
