Laniakea-scale region
Laniakea is a vast region of interconnected galaxy clusters defined by shared gravitational flows.
How big is it?
159.4 Mpc across
Diameter · rounded reference
A little perspective
About 9.63 times the distance of Distance to the Virgo Cluster.
Distance to the Virgo Cluster: This is the distance from the Milky Way to the Virgo Cluster, a nearby large cluster of galaxies.

Laniakea-scale region
An illustrative 520 million light-year span for a large-scale galaxy-flow region; boundaries depend on the model.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.
Distance to the Virgo Cluster
A rounded 54 million light-year distance anchor for the nearby galaxy cluster.
Defined examples — our methodology
The marked distance is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 159.4 Mpc
For comparison, this page uses diameter. This is labelled rounded reference: an explicit comparison model rather than a claim that every example has the same value.

The marked horizontal span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
