Recessional velocity of only 230 km/sec is too small to be a reliable indicator of distance, as the peculiar (non-Hubble expansion) velocity could be a substantial portion of the value. And as it turns out, the 10 million light years distance implied by the velocity is far lower than redshift-independent distance estimates of around 50 million light years. Using the presumably more accurate latter value, the apparent size of 3.9 by 1.1 arcmins implies a diameter of around 50 thousand light years.

Its recessional velocity of 435 km/sec is too small, in comparison to peculiar (non-Hubble expansion) velocities, to ensure an accurate distance estimate. And in fact, the distance corresponding to the recessional velocity is only 20 million light years, which is less than half the redshift-independent distance estimates of 50 to 55 million light years. Presuming a distance of around 50 million light years, its apparent size of 3.6 by 1.8 arcmins would correspond to a diameter of about 50 thousand light years.
