Distance
Distance is a numerical description of how far apart objects are. In physics or everyday discussion, distance may refer to a physical length, or an estimation based on other criteria . In mathematics, a distance function or metric is a generalization of the concept of physical distance...

Metre
The metre , symbol m, is the base unit of length in the International System of Units . Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole , its definition has been periodically refined to reflect growing knowledge of metrology...

- 1.2 Ym — 127 million light years — Distance to the closest observed gamma ray burstGamma ray burstGamma-ray bursts are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies. They are the most luminous electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several minutes, although a typical...
GRB 980425GRB 980425GRB 980425 was a gamma-ray burst that was detected on 25 April 1998 at 21:49 UTC. A gamma-ray burst is a highly luminous flash associated with an explosion in a distant galaxy and producing gamma rays, the most energetic form of electromagnetic radiation, and often followed by a longer-lived... - 1.3 Ym — 140 million light years — Distance to the Centaurus ClusterCentaurus ClusterThe Centaurus Cluster is a cluster of hundreds of galaxies, located approximately 155 million light years away in the Centaurus constellation. The brightest member galaxy is the elliptical galaxy NGC 4696...
of galaxies, the nearest large superclusterSuperclusterSuperclusters are large groups of smaller galaxy groups and clusters and are among the largest known structures of the cosmos. They are so large that they are not gravitationally bound and, consequently, partake in the Hubble expansion.-Existence:... - 1.9 Ym — 200 million light years — Diameter of the Local Supercluster

- 3.2 Ym — 340 million light years — Distance to the Stephan's QuintetStephan's QuintetStephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies of which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory....

It appears as a striking overdensity in the distribution of...
