1453 Fennia (provisional designation: 1938 ED1) is an inner main belt asteroid. It was discovered on March 8, 1938 by the Finnish astronomer Yrjö Väisälä at Iso-Heikkilä Observatory in Turku, Finland. The asteroid's name is the Latin word for Finland.[1]

In 2007, a team of astronomers made photometric observations of Fennia, and discovered that it is orbited by a moon. The moon is at least a quarter the size of Fennia itself, and has an orbital period of approximately 23 hours. The team also found that Fennia has a rotation period of 4.4 hours and is likely spheroidal in shape.[2]
