NGC 5203 is a 12.6 mag bright elliptical galaxy of the Hubble type "E-S0" in the constellation Virgo north of the ecliptic . It is estimated to be 297 million light years away from the Milky Way and has a diameter of about 160,000 ly.
In the same area of the sky are the galaxies NGC 5232 and IC 899 , among others .
The object was discovered on February 4, 1786 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as “vF, vS, easily resolvable, 240 power rather confirmed”. John Herschel noted during an observation with an 18-inch reflecting telescope in 1847: "vF, S, R, gbM, 15 arcseconds".
