HCG 87 is a compact group of galaxies listed in the Hickson Compact Group Catalogue.

This group is about 400 million light-years away [2] in the constellation Capricornus.

The group distinguishes itself as one of the most compact groups of galaxies, hosting two active galactic nuclei and a starburst among its three members, all of which show signs of interaction.

[3] This interaction, which astronomers have called visually, and scientifically, intriguing[4] is being examined to understand the influence of active nuclei on star formation histories.
