What is the hottest star? (solar system)?
Question:
Answer:
Even hotter than type O stars are the central stars of planetary nebulae. These are the cores of red giants that have lost their hydrogen envelopes and are on their way to becoming white dwarfs, The central star of NGC 2440 in Puppis has been measured at 220,000 K (395,000 °F). Neutron stars are even hotter, at up to 1 million K (1.8 million °F) , but they are also very tiny.
the sun is the hottest star!
I dunno, them yellow ones are mighty sexy too. Don't count them out!
The hottest blue stars are about 40,000 degrees at the surface, and many millions at the core - much hotter than the sun, which is 16 million in the core. We measure star temp at the surface, however, so the sun is a relatively cool star at about 4500 degrees on the surface.
The Sun is the only star in our solar system. Vega and Rigel are hot blue stars in the constellations Lyra and Orion.
The hottest star in the solar system is the Sun. It is also the coolest star in the solar system, being the only star here.
The hottest stars are the Wolf-Rayet stars, which have surface temperatures in excess of 150,000 F. There are believed to be fewer than 200 Wolf Rayet stars in our galaxy of 200 billion stars, making them quite rare. To the human eye they would have a distinct bluish tint, but in fact, their main output is in the ultraviolet, which our eyes do not respond to. Part of the reason for their rarity is that they have very brief lifespans of less than one million years.
Well because of the way you worded the queston the answer would be the sun becasue the solar system is the sun and its 8 planets. But yes the blue stars are hotter then the yellow and red stars.
