Is our sun a low mass star?
Low-Mass Stars fuse hydrogen into helium, the proton-proton cycle.
The classic low-mass star is the Sun.
Low-mass stars have large convection zones when compared to intermediate- and high-mass stars.
The star then becomes a Red Giant Star ..
What is big between Sun and Star?
The Short Answer: Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. … Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
What is largest known star?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
What is a dying star called?
supernovaeSome types of stars expire with titanic explosions, called supernovae. When a star like the Sun dies, it casts its outer layers into space, leaving its hot, dense core to cool over the eons. But some other types of stars expire with titanic explosions, called supernovae.
How does a star die?
Stars die because they exhaust their nuclear fuel. … Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’. What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – or, if there’s sufficient mass, a black hole.
What is the hottest star type?
blue starsThe hotter the star, the further up the spectrum you go. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. So the hottest stars in the Universe are going to be a blue star, and we know they’re going to be massive.
Which color star is the coolest?
Red starsRed stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
What is the hottest star color?
blueThe color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
Is the sun a main sequence star quizlet?
Terms in this set (12) A normal star that is undergoing nuclear fusion of hydrogen into helium. Our sun is a typical main sequence star.
What are the 7 types of stars?
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.
What is the difference between a star and a sun?
First of all, a star is a luminous celestial body, just like our sun. So our sun is a star. … So the biggest difference between a star and a planet is that a sun is massive enough for fusion. A moon is a celestial body orbiting a planet or asteroide.
Will our Sun become a black hole?
Our Sun, for example, is not massive enough to become a black hole. Four billion years from now when the Sun runs out of the available nuclear fuel in its core, our Sun will die a quiet death. Stars of this type end their history as white dwarf stars.
What kind of star is the sun?
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth’s atmosphere.
What is the biggest star in the universe?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
Why do stars twinkle?
The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. … To our eyes, this makes the star seem to twinkle.
