Objects in our sky are ranked by how bright they appear to the average person on Earth – a measure known as apparent visual magnitude. Over the course of a year, the apparent magnitude of a celestial body changes, due to two primary factors: firstly, we see a different sky throughout the course of the year, so a celestial body may not always be visible in our night sky; secondly, since the universe is constantly in motion, some bodies move further away from us with time. Though some objects are easy to spot in the sky, such as our beloved Moon, some are harder to spot unless you know where (or in which constellation) to look. For stargazers and amateur astronomers alike, read this list and see if you can find the 25 Brightest Objects in Space That You Can See With Your Naked Eye.
