NGC 4795 is a 12.2 likes bright barred spiral galaxy of Hubble type SBa in the constellation Virgo . It is an estimated 122 million light-years away from the Milky Way and has a diameter of around 90,000 ly. It is connected to NGC 4796 by gravity , and its eastern arm is already showing signs of this influence.
The object was discovered on January 23, 1784 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as “pretty bright, pretty large, brighter towards the preceding side”.
