Its visible galaxy is roughly 50,000 to 60,000 light-years across, depending on which published estimate you use and where you count its faint outer edge.
How far away is the Sombrero Galaxy?
M104 is roughly 30 million light-years away. NASA’s Hubble Messier catalog lists 28 million light-years, while NASA’s description of a Hubble image released in 2025 rounds the distance to around 30 million light-years. A 2016 study using Hubble observations and the tip of the red giant branch method measured 9.55 megaparsecs, or about 31 million light-years.
Those figures are rounded public descriptions or measurements made using different methods, not a meaningful disagreement about the galaxy’s location. The study’s authors noted that older estimates varied by method, and that the Tully–Fisher method may be poorly suited to M104’s unusual shape. NASA’s Messier 104 catalog entry, NASA’s 2025 Hubble image description, and the 2016 paper The Distance to M104 provide those estimates.
How big is the Sombrero Galaxy?
NASA describes M104 as 50,000 light-years wide. A NASA and Hubble Heritage Team educational lithograph gives 60,000 light-years across. It is most useful to treat the galaxy as roughly 50,000 to 60,000 light-years in diameter, rather than assign it a precise edge-to-edge size.

The difference reflects, in part, how the galaxy’s boundary is defined. Its bright disk is surrounded by a much larger, faint distribution of old stars, so an estimate based on the readily visible disk need not match one that includes dimmer outer structure. The 50,000-light-year figure appears in NASA’s 2003 Hubble image description; the 60,000-light-year estimate is in the 2004 NASA and Hubble Heritage Team lithograph. The 2016 study also discusses the galaxy’s larger stellar component.
Why does it look like a sombrero?
From Earth, M104 is seen nearly edge-on. Its bright central bulge resembles a hat’s crown, while the flat disk and prominent dark dust lane make a broad brim. The familiar shape is largely a matter of viewing angle: a galaxy can look very different when seen face-on than when viewed along the plane of its disk.

NASA describes M104 visually as a spiral galaxy. Its structure is more complex than the image alone suggests: the 2016 distance paper notes that its large bulge led to a historical spiral classification, while infrared observations of a larger surrounding spheroid have prompted some researchers to discuss an elliptical classification. That nuance does not change the obvious edge-on disk and dust lane seen in Hubble images.
How large does it look in Earth’s sky?
Physical diameter and apparent angular size are different measurements. NASA’s 2025 Hubble page says M104 appears about one-third as wide as the full Moon’s diameter in the sky. That comparison describes how much of the sky it covers, not how many light-years across it is.

The 2025 Hubble view is a mosaic assembled from multiple images because the galaxy is too large to fit within Hubble’s narrow field of view in a single image. See NASA’s 2025 image description for the angular-size comparison and mosaic context.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you see the Sombrero Galaxy without a telescope?
No. NASA’s Messier catalog lists an apparent magnitude of 8.0 and says M104 is beyond naked-eye visibility, though it can be spotted with a small telescope. NASA’s 2003 description likewise says a modest telescope can show it. The galaxy’s large apparent span does not make it bright enough to see unaided.

NASA’s catalog notes that May is the easiest time to find it through small telescopes. This is an observing tip, not a change in the galaxy’s distance or physical size. NASA’s M104 catalog entry gives its visibility and apparent magnitude.
