There are many things we do not know about the universe. No scientist can tell us how big the universe actually is, and where the universe begins or ends. What we know is that the universe is very big enough to exceed our imagination. And in that vast universe there are also giant things like galaxies, black holes, quasar groups and the like. Below is a list of the 10 largest “things” in the universe.
10. Ceres: the largest asteroid, alias dwarf planet
Ceres compared to the Earth and the Moon
An asteroid is a piece of matter that, like a planet, moves in a path around the sun. The biggest known asteroid is Ceres. Ceres follows a circulation course located between these Mars and Jupiter planets.Ceres is spherical, with a diameter of about 945 kilometers. The asteroid could count on promotion in 2006. Since that year, Ceres carries the title of ‘dwarf planet’. By the way, Ceres, when discovered in 1801 by Giuseppe Piazzi, was classified as the chitest planet.
9. UY Scuti: the greatest star in the universe
Our sun may then be many times larger than the earth, it is not compared to the star UY Scuti. This red giant is in the zodiac sign Schild, a sloppy 9500 light year far. UY Scuti’s diameter is about 1700 times larger than this of our sun. Suppose you could travel with the speed of light, you would still have seven hours left to cycle around UY Scuti!
8. WASP-17b: So far the largest planet
With a diameter that is 22 times larger than the earth’s diameter, WASP-17b is the largest known exoplanet . It is a giant exoplanet in the constellation Scorpio, which consists mainly of gas. Although her diameter is twice as large as Jupiter’s diameter, her mass is only half. Big but lean!
7. The largest star system: IC1101
The star system IC1101, found in the zodiac sign Snake about 1 billion light years from us, is the largest star system observed so far. The diameter of IC1101 is no less than 5.5 million light years. The size of IC1101 is likely to be explained by the many collisions that the galaxy has undergone with other systems. Compared to this, our own Milky Way is a dwarf, with a diameter of ‘only’ 100,000 light years …
6. Radiotherapy systems
Radiostream systems are bones under the galaxies. They are mostly elliptical systems, but with two huge “lobes” that come out of their core. These lobes have a diameter of hundreds of thousands of light years, and emit powerful radio radiation. Very interesting for astronomers because because of this radio radiation one can observe the radio systems at a long distance.
5. The biggest black holes
They are popular in science fiction films : black holes that cheer all the celestial bodies in their neighborhood eagerly. The biggest black holes that have been observed are called ‘super heavy black holes’. These have a mass that is millions of times greater than the mass of our sun. How does she develop? A ‘plain’ black hole can not control if you put it near a lot of matter. It just consumes all matter in its surroundings. The result: a super heavy black hole! Obesity under the black holes, therefore.
4. Superholes in the universe
A superhole is, as the name indicates, a kind of emptiness in the universe that contains no or near no galaxies. Although the universe contains unusually many galaxies, there are areas in which there is little or nothing. The diameter of a superhole is hundreds of millions of light years. Imagine making a trip in such a superhole: hundreds of millions of years travel at the speed of light, to see nothing! A travel agency will not offer such a trip soon …
3. A Super Large Large Quasar Group

Quasars are galaxies from the very beginning of the universe. We can still see these on earth. Quasars are so far removed from us, that their light takes over billions of years to reach the Earth. Quasars tend to unite in groups that take enormous dimensions. This is called LQG’s: Large Quasar Groups. In 2013, a superlative LQG was discovered, with a diameter of only 4 billion light years! To move from one end to the other, you should travel 4 billion years at the speed of light.
2. The big GRB wall

In 2013, a team of American and Hungarian astronomers discovered a super-wide galactic structure.The discovery was based on eruptions of gamma radiation in galaxies. Such eruptions are called GRBs (gamma ray bursts). An extreme concentration of GRBs led to the discovery of a huge supercluster of galaxies, with a diameter of no less than 6 to 10 billion light years! This supercluster is called the Great GRB wall (the big GRB wall).
1. The cosmic web
Andrew Pontzen and Fabio Governato
Studies of the universe seem to indicate that the universe is organized like a spider web. There would be connections between clusters of galaxies. These compounds can be compared to the spiders webs.They consist mainly of so-called ‘dark matter’, matter that does not transmit radiation and thus is not perceptible on earth. The cosmic web would be the “skeleton” of the universe, which holds together all clusters of galaxies. If this theory is correct, the cosmic web is undoubtedly the largest structure that exists in the universe.
