What is the hottest M&M?

In general, a star's temperature determines its color, from red to blue-white. Spectral types are named with a letter. The seven main types are M, K, G, F, A, B and O. M stars are the coldest stars and O stars are the hottest.

Which type is 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 correct order of the star's surface temperature from the hottest to the coolest?

From hot stars to cool, the order of stellar types is: O, B, A, F, G, K, M. (A traditional mnemonic for this sequence is “Oh Be A Fine Girl [or Guy], Kiss Me.”) Additional letters have been used to designate novas and less common types of stars.

Which kind of star is hottest?

White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.

What are the 7 different types of stars temperature?

There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B are uncommon, very hot and bright. M stars are more common, cooler and dim.

Which M

What does OH a fine girl kiss me mean?

Every student in introductory astronomy learns the mnemonic “Oh Be a Fine Girl/Guy, Kiss Me”, which is a way to remember the spectral classification of stars. Here's how it works: the color of a star is determined by its temperature, as I outlined previously.

Is a black hole a star?

Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)

What is the hottest in the universe?

The hottest thing in the Universe: Supernova

The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun's core.

What is the hottest Sun?

The hottest part of the Sun is the core, at 28,080,000°F, on average.

What is the hottest Sun color?

So you could say the Sun is now middle-aged. It's about halfway through its life. So blue giants are hottest, white stars are very hot, but there are also orange stars that burn less hot. There are even red stars, which are a bit cooler again.

Which stat is the hottest?

The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.

Is the sun the hottest star?

No, the Sun is not the hottest star; there are many stars much hotter than the Sun! You can tell the approximate temperature of a star by looking at its color. The coolest stars are red, then orange, then yellow (like our Sun). Even hotter stars are white and then the hottest stars are blue!

Which is hotter O or B?

Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type).

What is a b0 star?

B stars are hot stars defined by the presence of hydrogen (H) and neutral helium (HeI) in the optical spectra.

What star is hotter than the Sun?

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.

What is the coolest star type?

The spectral sequence is also a colour sequence: the O- and B-type stars are intrinsically the bluest and hottest; the M-, R-, N-, and S-type stars are the reddest and coolest.

How hot is the moon?

Taking the Moon's Temperature

Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.

How hot is lava?

The eruption temperature of Kīlauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit). The tube system of episode 53 (Pu'u O'o eruption) carried lava for 10 kilometers (6 miles) from the vent to the sea.

How hot is a lightning bolt?

In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).

How hot is a black hole?

Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.

Is lightning hotter than lava?

Which is hotter the sun lava or lightning? Lightning because lightning is 70 000 degrees Fahrenheit. Lava is just 2 240 degrees Fahrenheit. So lightning is hotter than lava.

Is lava hotter than the Sun?

Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.

Are white holes real?

The short answer, unfortunately, is no. White holes are really just something scientists have imagined — they could exist, but we've never seen one, or even seen clues that one may exist. For now, they are an idea. To put it simply, you can imagine a white hole as being a black hole in reverse.

What is white black hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
