Which has a longer life bigger stars or smaller stars?

Which has a longer life bigger stars or smaller stars?

1) The bigger a star is, the longer it will live. 2) The smaller a star is, the longer it will live. A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.

Are bigger or smaller stars brighter?

The closer a star is to us, the brighter it will appear. Also, stars come in a variety of sizes and brightnesses. Larger stars usually shine more brightly than smaller stars do. So, how bright a star appears in the night sky depends on its size and how far away from us it is.

Why do larger stars have shorter lifespans than smaller stars?

Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.

What do different sized stars mean?

Stars come in different sizes. A star like our Sun with one solar mass is called a G star; it has a yellow colour and the fusion rate allows the star to live for around 10 billion years. Smaller stars have much lower fusion rates since the pressure and temperature in their core is lower than in other stars.

Are stars classified by their sizes?

Stars come in huge range of different sizes. Neutron stars can be just 20 to 40 km in diameter, whereas white dwarf can be very similar in size to Earth’s. The largest supergiants, on the other hand, can be more than 1500 times larger than our Sun.

What type of stars are the hottest?

O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. These stars have few absorption lines, generally due to helium. These stars burn out in a few million years. B stars have temperatures between about 10,000 and 20,000K.

What is the smallest frequency?

Extremely low frequency

Frequency range 3 to 30 Hz
Wavelength range 100,000 to 10,000 km, respectively
