NGC 404 is a spiral galaxy located approximately 10 million light-years away in the constellation Andromeda. It is often referred to as the "Mirach's Ghost" because it appears close to the bright star Mirach, which can make it challenging to observe. This galaxy has a diameter of about 50,000 light-years and is classified as a type SA spiral galaxy. NGC 404 is notable for its relatively low surface brightness, making it less prominent in the night sky compared to other galaxies.
