Below is an ordered list of the largest stars currently known by radius.The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,288 mi).. The exact order of this list is very incomplete, as great uncertainties currently remain, especially when deriving various important parameters used in calculations, such as stellar luminosity and effective temperature.


Of course, this is just a tiny list of stars. There are some enormous lists of stars out there. One of the most comprehensive is the SIMBAD database. This is an online database that contains 4.3 ...


the "Methuselah star" List of oldest stars: Youngest Stars are being formed constantly in the universe so it is impossible to tell which star is the youngest. For information on the properties of newly formed stars, See Protostar, Young Stellar Object and Star Formation.


Historically, the most prominent stars were grouped into constellations, and the brightest stars gained proper names. The below is the list of top 10 largest stars known in the universe: 10. Sirius. The brightest star in the night sky is between 200 and 300 million years old. Sirius can be seen from almost everywhere on the Earth’s surface.


Universe Today has articles on what is the North Star and types of stars. Here’s another article about the 10 brightest stars . Astronomy Cast has an episode on famous stars .


Today you’re going to read about some of the most bizarre stars in existence. The universe is estimated to have about 100 billion galaxies and roughly 100 billion stars are in each galaxy. With so many stars there are bound to be a few oddballs.


So how do astronomers figure out how many stars are in the universe? The first sticky part is trying to define what "universe" means, said David Kornreich, an assistant professor at Ithaca College ...


Stars are enormous spheres of ignited gas that light the cosmos, and seed it with the materials for rocky worlds and living beings. They come in many different types and sizes, from smouldering white dwarfs to blazing red giants.


The Brightest Stars. This is a list of the 300 brightest stars made using data from the Hipparcos catalogue. This is every star brighter than magnitude 3.55. The stellar distances are only fairly accurate for stars well within 1000 light years.


Stars are immense balls of burning plasma. Yet, aside from the Sun, they look like tiny pinpoints of light in the sky. Our Sun is not the biggest or the smallest star in the universe.Technically, it's called a yellow dwarf. It's much bigger than all the planets combined, but not even medium-sized by the standards of all the stars.
