About NGC 3892
What you are looking at
NGC 3892 is a lenticular galaxy: a disc galaxy that has largely used up the gas it needs to form new stars, so its disc is smooth and has no spiral arms. It is tilted about 31° to our line of sight, enough to show both the shape of its arms and the depth of its disc. From edge to edge its visible disc spans about 75,000 light-years, about 76% of the Milky Way’s width.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a member of a group of galaxies. It is cited in 73 scientific papers indexed by SIMBAD, and recorded there under 9 different catalogue designations.
When this light set out
What a telescope records of NGC 3892 is light that left it about 84 million years ago; on Earth, dinosaurs were at their peak. The galaxy is moving away from us at about 1,749 km/s (3.9 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 3892 sits within the constellation Crater. It is best placed on spring evenings: around 9:30 pm in April it stands about 39° high in the south, seen from the middle of the United States.
Its neighbours
At almost the same distance from us, and so its neighbours in space as well as on the sky: NGC 3779 (2.3° away on the sky, at least 3,330,000 light-years from it).
By apparent size it is number 491 of the 12,657 galaxies on the Galaxy Origins register.

What is sold
A print of this galaxy and the record of the calculation, once. When it sells it leaves the register and is not offered again. We assign no names and no ownership — nobody can sell you those.
At 3.1 arcminutes this is a Exceptional galaxy, which is the tier where a real photograph shows clear structure and dust lanes. The tier comes from the measured diameter, not from a price list.
