The universe is that which is not able to comprehend our mind. The human mind is simply not able to understand and analyze its true dimensions.
No one knows whether the Universe is finite or not, but it is scientifically proven that it is constantly expanding. This place combines amazing objects such as nebulae, galaxies, quasars, clusters of stars, black holes, quasars. Let's talk about the largest objects in the universe.
The largest asteroid in the universe
The largest asteroid is called Vesta, and it is recognized as the brightest visible asteroid that can be seen in the starry sky even without a telescope or telescope. The dimensions of the asteroid are 578x560x478 kilometers. It has a slightly elongated asymmetric shape and can even be attributed to dwarf planets such as Mercury. There is an asteroid in the belt between Jupiter and Mars. A celestial body was discovered in 2010 using the Dawn apparatus. It is worth saying that the threat of an asteroid due to high gravity acting on it from Jupiter to the Earth does not represent.
Largest planet
The championship of the largest planet in the solar system holds Jupiter, which can accommodate hundreds of such planets as the earth. But in the depths of the visible Universe, a real monster lurked.
Until 2011, the planet TrES-4 had the status of the largest planet in the universe.. It was discovered in 2006. It is located at a distance of one and a half thousand light years from the earth. This is a huge ball, which consists of hydrogen, and its mass is 20 times greater than the mass of Jupiter. The temperature on this planet reaches 1260 degrees Celsius and it is a huge and incredibly hot gas giant. Probably this planet is definitely not suitable for organic life.
Now the largest planet in the Universe is HAT-P-32b (at a site accessible for study by scientists today).The radius of the planet HAT-P-32b is 145,629 km, which corresponds to 2,037 the radius of the largest planet in the solar system - Jupiter. The mass of the exoplanet is 0.941 of the mass of Jupiter. The object was first discovered in 2004, but the status of the planet was assigned only on June 08, 2011.

If we talk about exoplanets, on which life can hypothetically exist, then one of the largest planets in the Universe is Gliese 581, which was discovered in 2007 at a distance of 20 thousand light-years from Earth in the Chilean observatory of La Silla using Doppler shift.
Biggest star
Scientists have discovered the largest star in the universe. She is called UY in the constellation Shield. Its size is 1700 times larger than the size of our Sunand the radius of the star reaches 1,054,378,000 miles. The scale is simply grandiose, and not amenable to the imagination of a simple layman. If you put the star UY in the position of the Sun, then it will go beyond Jupiter. You can see this star from a conventional telescope, as it shines quite brightly. The star is removed from the Earth at a distance of 9500 light years. Read more about the biggest stars in our article: the biggest stars in the universe.
Biggest black hole
The largest supermassive black hole in the visible Universe was discovered in the constellation Perseus at a distance of 228 light years from Earth. This black hole is in the galaxy: NGC 1277. This black hole contains just a giant amount of matter, which is about twelve billion masses of our Sun.
It turned out that this black hole weighs about 15 percent of the mass of the entire galaxy, although usually black holes weigh no more than one and a half percent. By the way, such a small black hole is located in the center of our Milky Way.Scientists agreed that a galaxy in which there is a supermassive hole is very strange, since the nature of the formation of such an object is incomprehensible to physicists.
Largest galaxy
The largest galaxy in the Universe is called IC 1101. It is a large supergiant located in the center of the cluster of galaxies Abell 2029. The galaxy is located at a distance of one billion light-years from Earth in the constellation Virgo. This is a CD-class galaxy with a diameter of 7 million light years. The object is considered the largest among the known galaxies that have been discovered for all the time of cosmological research.
Galaxy IC 1101 contains more than one hundred trillion stars. If this galaxy was in place of the Milky Way, then it would absorb not only it, but also the Andromeda Nebula, the Triangle galaxy, the Big and Small Magellanic clouds.
Shapley Supercluster
The Shapley Supercluster is a huge cluster of stars that was discovered in 1989. It has a high density of stars. According to preliminary estimates, in the Shapley supercluster there is a concentration of stars for more than 500 million light years. It also has large galaxies A3560, A3558 and A3559. In total, there are about twenty-five galaxies in the Shapley supercluster.
The biggest pulsar
The largest pulsar, which is a bright pulsating star with superdense mass, was discovered in the region of the Tarantula nebula. It was discovered using a powerful gamma-ray telescope in 165 thousand light years from the Milky Way galaxy. A pulsar formed after a star burst, and its core became a powerful neutron star. With a diameter of a couple of kilometers, the mass of the pulsar is twenty solar masses. Its gamma radiation is five times higher than that of the famous pulsar from the Crab Nebula. The pulsar rotates at a speed of twenty revolutions per second, emitting powerful gamma radiation.
Biggest quasar
In 2015, scientists from the University of Arizona discovered the largest quasar on the edge of the visible Universe, located near a supermassive black hole. The facility was named SDSS J0 + 2802. For the first time, quasars were discovered back in the middle of the last century, and these are the brightest objects in the Universe that are formed after the end of the star’s life cycle. The end of a star’s life cycle can follow two scenarios. It can decrease to the size of a superdense star or expand, becoming later a quasar.
The discovered quasar has more than one hundred thousand masses of the sun, and it is powered by a giant black hole. Scientists not only studied the quasar itself, but also measured the mass of the black hole next to it. The object is located at a distance of more than 6 million light years from the earth.
Our universe is unique. It is fraught with many secrets that humanity does not yet know soon. Supergiant objects exist both in our solar system or the Milky Way galaxy, and beyond these cosmic objects. It is possible that outside the visible Universe there are even larger objects than those that we cited in this article.
