About the Local Sheet

The map lists it as a large-scale structure and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

The flat wall of galaxies we live in: the Local Group and its neighbours within about 7 Mpc lie in a sheet inclined only 8° to the supergalactic plane, with giant galaxies scattered just 0.23 Mpc above or below its midplane (McCall 2014). The whole sheet moves away from the Local Void at about 260 km/s (Tully et al. 2008).

Key numbers

Distance1.37 million light-years (0.42 Mpc)
Distance methodredshift-independent (literature)
Supergalactic coordinatesSGL 336.2°, SGB +12.6°
On the mapThe dashed circle marks its approximate size around its centre. Structures this large have no sharp edge, and the circle is not drawn to an exact shape.
Sizeabout 46 million light-years across

Where it is

Its place in the universe, from the inside out: Local Group › Virgo Supercluster › Laniakea Supercluster › Observable universe.

Zoom out to see it in context: Virgo Supercluster, a view about 230 million light-years across.

From Wikipedia

The Local Sheet or the Coma–Sculptor Cloud is a nearby galaxy filament and an extragalactic region of space where the Milky Way, the members of the Local Group, and other galaxies share a similar peculiar velocity.
