548 Kressida is a minor planet orbiting the Sun. This object was discovered by German astronomer Paul Götz in 1904. It is named after the theatrical character Cressida. This stony S-type asteroid is orbiting at a distance of {{val|2.28|ul=AU}} from the Sun, with an orbital eccentricity (ovalness) of 0.185 and a period of {{cvt|1259.3|days|years|2|disp=out}}. The orbital plane is inclined at an angle of 3.87° to the ecliptic.
Photometric observations of this asteroid from 2021 were used to produce a light curve showing a rotation period of {{val|11.930|0.017|u=hours}} with a brightness amplitude of {{val|0.44|0.02}} in magnitude.
