Which stars have the coolest surface temperature?

Astronomers classify stars into different types depending on their temperatures. These types are O, B, A, F, G, K, and M, where type O stars are the hottest and type M stars are the coolest.

Which of the following stars are the coolest?

Red stars
Red 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.

Which of the following stars has the lowest surface temperature?

Which star has the lowest surface temperature? Antares, with a spectral type of M1 (the furthest from O in OBAFGKM), has the lowest surface temperature.

Which color stars have the coolest surface temperature quizlet?

(Notice that temperature is related to color, and follows the order of the colors in the rainbow: Blue (or violet) stars are the hottest, while red stars are the coolest.)

Which of the following star colors sorts its surface temperature from coolest to hottest?

blue
Cooler objects will have redder colors. So, at the crudest level we can simply sort them out by color with the red stars being the coolest and the blue stars being the hottest.

Which of the following types of stars is the coolest quizlet?

Blue (or violet) stars are the hottest, while red stars are the coolest. In the parts that follow, the H-R diagrams show the correlation between color and temperature on the horizontal axis. Five stars are shown on the following H-R diagrams. Rank the stars based on their surface temperature from highest to lowest.

What color stars have the hottest surface temperature?

blue-white
A star’s color provides a direct measurement of its surface temperature; the hottest stars shine blue-white, while the coolest are dull orange or red. In turn, the temperature indicates how much energy a given area of the star’s surface radiates into space every second.

What color are the coolest stars quizlet?

Blue or white are the hottest and red is the coolest. Our own star, the Sun, is nearly in the middle of both the temperature and luminosity scales relative to other stars.

Which has the highest surface temperature a red star white star or blue star quizlet?

Red stars have the lowest surface temperature, followed by yellow stars being “the middle surface temperature” and blue stars having the highest surface temperature.

Which star has a surface temperature?

Spectral types are a measure of the surface temperatures of stars and are letter designations: O, B, A, F, G, K, and M. Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins. On the other extreme, type M stars have the lowest surface temperatures and can be as cool as 3,000 K.

What color are the hottest and coldest stars?

The colour provides a fundamental piece of data in stellar astrophysics—the surface temperature of the star. The hottest stars are blue and the coldest are red, contrary to the use of colours in art and in our daily experience.

Which has the highest surface temperature?

planet Venus
In solar system the planet Venus have the highest surface temperature. 480 degree c.

What type of stars are bright and cool?

The Supergiants are cool stars, which are very large and very bright. They are located towards the top right of the graph. The Giants are cool stars, which are a little smaller and dimmer than the Supergiants. The White Dwarfs are very hot stars, which are small in size and relatively dim.

Which star has the lowest luminosity?

Red dwarfs
A red dwarf is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.

Which planet has the highest surface temperature which planet has the lowest surface temperature?

Mercury: The Mercury is the smallest and fastest planet, Mercury is the closest planet to the Sun and orbits around it every 88 Earth days.

Which planet has the highest surface temperature ?
Planets Temperature
Venus 880°F (471°C)
Earth 61°F (16°C)
Mars minus 20°F (-28°C)
Jupiter minus 162°F (-108°C)

What is the coldest temperature in?

Absolute zero, then, is the point at which all molecular motion stops — minus 459.67 degrees Fahrenheit, or minus 273.15 degrees C. Scientists have even developed a special scale for extremely cold temperatures, called the Kelvin scale, where zero Kelvin corresponds to absolute zero.

Why Venus is the highest surface temperature?

Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. … The heat becomes trapped and builds up to extremely high temperatures.

Which planet has the coldest atmosphere?

Uranus
The seventh planet from the sun, Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant. Despite the fact that its equator faces away from the sun, the temperature distribution on Uranus is much like other planets, with a warmer equator and cooler poles.
