548 Kressida 
Summary
Kressida (minor planet designation: 548 Kressida) is a minor planet orbiting the Sun. This object was discovered by German astronomer Paul Götz in 1904.[2] It is named after the theatrical character Cressida. This stony S-type asteroid is orbiting at a distance of 2.28 AU from the Sun, with an orbital eccentricity (ovalness) of 0.185 and a period of 3.45 yr. The orbital plane is inclined at an angle of 3.87° to the ecliptic.[1]
