Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A. The orbit of Neptune (white oval) is included for comparison. The central black hole of the Phoenix Cluster is the engine that drives both the Seyfert nucleus of Phoenix A, as well as the relativistic jets that produce the inner cavities in the cluster center.

The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished; i.e., the Atlas V series is only counted once for all its configurations 401–431, 501–551, 552, and N22.
This is a comparison list of intercontinental ballistic missiles developed by various countries. ICBMs by country. Legend for launch system status in below table: ...
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than 50 metric tons (110,000 lb) [1] [2] by the United States and as more than 100 metric tons (220,000 lb) by Russia. [3]
Ton 618 → TON 618 – No sources besides SIMBAD uses this version of the name. Peer-reviewed papers, including the paper that gave the black hole it's mass estimate, have used the capitalised version of the name. To add further, NASA uses the capitalisation as well.
