The Leo IV Dwarf Galaxy (Leo 4 矮小銀河) PGC 4713561

Leo IV is said to be the smallest and ultra faint dwarf galaxy among the Leo dwarf galaxies.
According to the current observation results, it is a galaxy made up of many DARK MATTER, so it is natural for it to be faint.
I can't tell where it is even in the Hubble photo, but the coordinates seem to be here.

Leo IVはLeo矮小銀河の中で最少でウルトラ淡い矮小銀河だそうだ。
今の観測結果によると多くのDARK MATTERで構築されいる銀河だそうなので淡いのは当たり前なのだろう。
Hubbleの写真でもどこにそれがあるかわからないが、座標はここのようだ。
