What else can I help you with?
Is it true or fault that A white dwarf star is about the same size as the sun?
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
True or false. our sun is a white dwarf star?
False. The sun is a yellow main sequence star.
How big is a brown dwarf?
There really is no answer. A black dwarf is simply a white dwarf that has gone out, after it has radiated all its heat. This process, however, takes an enormous amount of time and our universe is not old enough to acommodate it. Consequently, there is no such thing as a black dwarf anywhere in the universe to begin with, it is a theoretical concept. Strictly speaking, I wouldn't call a black dwarf a "star" either. It was once a star, it now is ("will be" to be precise!) a dead celestial body, a "stellar remnant" as it is called. If I should take a guess, however, I'd say it's smaller than a planet, given that this is the average white dwarf's size. The energy (heat) that it has lost will probably result in a loss in mass (remember E=mc2?)
What is the difference between a true planet and a dwarf planet?
The difference is that a dwarf planet is not or no longer a true planet.To be a true planet it must fit these criteria:1.Orbit the Sun2. Be spherical(rounded shape)3. Be able to clear its path of any objects in the way such as debrisPluto was unable to fit these criteria so is now a dwarf planet :)
What star is so small in mass that its core never gets hot enough to sustain nuclear fusion reactions?
A brown dwarf is a star with a mass between that of a giant planet and a small star. It lacks sufficient mass to sustain hydrogen fusion in its core like a true star, so it emits light and heat from residual energy.
Is a star bigger than a planet?
Yes, a star is generally much larger than a planet. Stars are massive celestial bodies that generate light and heat through nuclear fusion, whereas planets are smaller bodies that orbit stars.
Is it true or fault that A white dwarf star is about the same size as the sun?
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
Is it true or that a white dwarf is a large star capble of fusing elements?
no
What is the biggest a star can get?
some stars are a 1000 times bigger than our star(sun) so they are ginornmous. so no matter how big a star we find, in time we will find one biggert than that one. there is no true number in size
A brown dwarf is what's left when a large star explodes true or false?
False. A brown dwarf is a failed star that cannot sustain nuclear fusion. When a star explodes it will leav behind either a neutron star or a black hole depending on its mass.
True or false. our sun is a white dwarf star?
False. The sun is a yellow main sequence star.
If a is bigger than b and b bigger than c which statement must be true?
if a is bigger than b and b is bigger than c a must be bigger than c... Transitivity
Is a rhino bigger than a cat?
true, a rhino is bigger then a cat.
It is true that ther are stars bigger than the sun?
yes it is true
What is a brown dwarf and is it different from a white dwarf star?
A white dwarf is the remnant of a massive star that has shed much of its mass. The dwarf starts out very hot but slowly loses its heat as it no longer has the mass or the hydrogen to carry on with fusion.A brown dwarf is a celestial body that doesn't have sufficient mass to initiate hydrogen fusion and thereby become a true star. They have heat due to their initial gravitational contraction or maybe even a brief deuterium, lithium fusion stage but are now little more than a (hot) giant planet.
Is it true that a battlenose dolphin has a bigger brain than a human?
yes it is true
Do dwarf stars emit light?
Brown Dwarfs (maybe not true stars)Red Dwarfs (on the main sequence)Orange Dwarf (on the main sequence)Yellow Dwarfs (stars smaller than our sun but on the main sequence)White Dwarfs (old stars that have run out of hydrogen and are now off the main sequence)Neutron Stars (old large stars who's cores have collapsed during a supernova)---------------------------------------------------------------------------------Red dwarf - Like Proxima Centauri.White dwarf - A degenerate star. The remains of a Sun like star.Yellow dwarf - A G type main sequence star, like our own SunBlue dwarf - A hypothetical star formed from a red dwarf.Brown dwarf - A star that did not have enough mass to initiate nuclear fusion.Black dwarf - A hypothetical star formed when a white dwarf has cooled to absolute zero.Orange dwarf. A K type main sequence star, like Alpha Centauri B
