Here are our picks of the top 10 immense things in space
950Km diameter (average)
Discovered in 1801, Ceres makes up a third of the total mass of the asteroid belt between Mars and Jupiter.
9Biggest object in our solar system
The yellow dwarf star around which we orbit comprises over 99.8 percent of the total mass of our solar system.
8Biggest known planet
GQ Lup b
30 times the radius of Jupiter
This immense exoplanet, detected orbiting a star some some 457 light years from Earth, may have a mass up to 36 times that of Jupiter and is fiercely hot- possibly 2,650 Kelvin.
7Largest structure in the universe
Huge Large Quasar Group (Huge-LQG)
4 billion light-years across
In 2013, an international team detected a chain of some 73 quasars stretching so far that its existence challenges the fundamental Cosmological Principle.
6Biggest black hole
Centre of NGC 1277
17 billion solar masses
This supermassive black hole, at the centre of the NGC 1277 galaxy 220 million light-years away, has a mass 17 billion times greater than our Sun – itself about two nonillion kg.
Six-million light years across
This supergiant elliptical galaxy, discovered in 1790 by William Herschel, at the centre of the Abell 2029 cluster is about one billion light-years away. Our own galaxy, the Milky Way, is a mere 100,000 light-years across.
4Biggest water cloud
Around quasar APM 08279+5255
40 billion times the mass of Earth
In 2011, researchers discovered a vast cloud of water vapour surrounding a quasar some 12 billion light-years away. The cloud holds enough water to fill the Earth’s oceans 140 trillion times over.
Visible tail 35 degree
The spacecraft Ulysses passes through the tail of this comet in 2007 and detected ionised gas at a distance of 225 million km behind the nucleus. The ‘shocked wind’ behind the comet was larger still, making McNaught reportedly the largest comet ever discovered.
250 million light-years across
An area of space containing nearly no objects (though a few galaxies are present), this void is around 700 million light years from earth.
1,530 solar radii
Measuring distant stars is tricky – determining the edge of the star can be made difficult by solar winds – but the Royal Astronomical Society believes the red supergiant, which is about 1,000,000,000Km across and some 16,000 light-years from earth, is the largest.
