What do stars depend on?

What do stars depend on?

The fate and life of a star depends primarily on it’s mass. All stars begin their lives from the collapse of material in a giant molecular cloud.

• order from largest to smallesr semimajor axis.

What 2 factors does the brightness of stars depend on?

The apparent brightness of a star depends on both its luminosity and its distance from Earth.

What is the origin of all stars?

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Where on Earth can you stand and over the entire year see the entire sky?

(The north celestial pole is defined as the point in the celestial sphere directly above Earth’s North Pole. So, if you are at the North Pole, the north celestial pole must be directly above your head). Where on Earth can you stand and, over the entire year, see the entire sky? the tilt of the Earth’s axis.

Do stars actually move?

The stars are not fixed, but are constantly moving. The stars seem so fixed that ancient sky-gazers mentally connected the stars into figures (constellations) that we can still make out today. But in reality, the stars are constantly moving. They are just so far away that the naked eye cannot detect their movement.

What makes up the Stars in the night sky?

All stars are made primarily of hydrogen, smaller amounts of helium, and traces of other elements. The stars we can see with the naked eye in the night sky all belong to the Milky Way Galaxy, the huge system of stars that contains our solar system.

Which is the faintest star in the night sky?

The faintest stars visible to the naked eye are 6th magnitude. As originally applied by Hipparcus and others, this was a qualitative ranking, as they had no reasonable means of independently measuring brightnesses other than comparing them by-eye to other stars in the sky.

Why are some stars dimmer than others in the sky?

Some look dim because of their age, or because they’re far away. There’s no way to tell just by looking at a star what its age is, but we can tell brightness and use that to learn more. Stars are massive shining spheres of hot gas that exist in all galaxies across the universe.

What happens to the energy of a star when it is sufficiently dense?

When the stellar core is sufficiently dense, hydrogen becomes steadily converted into helium through nuclear fusion, releasing energy in the process. The remainder of the star’s interior carries energy away from the core through a combination of radiative and convective heat transfer processes.
