NGC 5898 is an 11.4 mag bright elliptical galaxy of the Hubble type E0 in the constellation Libra on the ecliptic . It is estimated to be 92 million light years away from the Milky Way and about 75,000 light years in diameter. Together with NGC 5903 , it probably forms a gravitationally bound galaxy pair.
In the same area of ​​the sky is u. a. the galaxy IC 4538 .

The object was discovered together with NGC 5903 on May 21, 1784 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as "Two, nearly parallel 7 'distant, Both vF, not vS, R." During an observation with an 18-inch reflector telescope in 1847, John Herschel noted "pB, R, pgbM, 15 arcseconds".
