220 Stephania is a Main belt asteroid. It is a P-type asteroid, meaning it is relatively dark and composed of organic rich silicates, carbon and anhydrous silicates.[citation needed]

It was discovered by Johann Palisa on May 19, 1881 in Vienna. It was the first discovery he made after transferring to the observatory from Pola.[1]

The name honours Crown Princess Stéphanie, wife of the heir-apparent Crown Prince Rudolf of Austria. The couple was married the year the asteroid was discovered. It was the first time that a naming commemorated a wedding and was given as a wedding gift.[1]

Lightcurve data has also been recorded by observers at the Antelope Hill Observatory, which has been designated as an official observatory by the Minor Planet Center.[2]
