Are stars really planets?

Answer 1

The sun is our closest star. The stars if they are still there as the light from them takes thousands of years to reach here are not planets. The stars are bright due to the light they emit from them like the sun. Planets dont emit light they bounce if of the closest polaris body (sun).

Answer 2

A star is a massive, luminous ball of plasma. Stars group together to form galaxies, and they dominate the visible universe. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth, including daylight. Other stars are visible in the night sky, when they are not outshone by the Sun. A star shines because nuclear fusion in its core releases energy which traverses the star's interior and then radiates into outer space. Without stars, life and most atomic elements present in the Universe would not exist.

Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate. Other characteristics of a star that are determined by its evolutionary history include the diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertzsprung-Russell, allows the current age and evolutionary state of a particular star to be determined.
state of a particular star to be determined.

A star begins as a collapsing cloud of material that is composed primarily of hydrogen along with some helium and heavier trace elements. Once the stellar core is sufficiently dense, some of the hydrogen is steadily converted into helium through the process of nuclear fusion. The remainder of the star's interior carries energy away from the core through a combination of radiation and convective processes. These processes keep the star from collapsing upon itself and the energy generates a stellar wind at the surface and radiation into outer space.

Once the hydrogen fuel at the core is exhausted, a star of at least 0.4 times the mass of the Sun expands to become a red giant, fusing heavier elements at the core, or in shells around the core. It then evolves into a degenerate form, recycling a portion of the matter into the interstellar environment where it will form a new generation of stars with a higher proportion of heavy elements

Answer 3

STARS : A star is a massive, luminous ball of plasma. Stars group together to form galaxies, and they dominate the visible universe. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth, including daylight. Other stars are visible in the night sky, when they are not outshone by the Sun. A star shines because nuclear fusion in its core releases energy which traverses the star's interior and then radiates into outer space. Without stars, life and most atomic elements present in the Universe would not exist.
PLANETS:
The International Astronomical Union defines "planet" as a celestial body that, within the Solar System,

(a) is in orbit around the Sun;
(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; and
(c) has cleared the neighbourhood around its orbit;
or within another system,

(i) is in orbit around a star or stellar remnants;
(ii) has a mass below the limiting mass for thermonuclear fusion of deuterium; and
(iii) is above the minimum mass/size requirement for planetary status in the Solar System.

Answer 4

No, when you look into the night skies you see a lot of points of lights but these are caused by a number of different things.

Some are stars which are suns, just like ours which may, or may not have planets in orbit around them that you cannot see. They produce their own light.

Some are galaxies, clusters of stars so far away that they appear to be a single point of light.

Some are planets, but you see a planet as a point of light because it reflects the light of our sun back to us.

And some are satellites... they'll be the ones moving across the sky.. the international space station is the easiest of these to see.


Always makes me chuckle when some fool posts bad answer ratings just for the sake of it. My comiserations to others in this question who have posted useful answers only to have some dunce flag it as a bad answer. There really are too many retards on Yahoo answers.

Answer 5

The only planets you see are in our solar system and you've named just about all the visible planets. Most everything else you see are stars. There are a few nebulae like Orion and some of the ones in Sagittarius that are visible and about 3 galaxies; two of which are only visible in the southern hemisphere or close to the equator.

Answer 6

no stars are not planets.but the origins of them is similiar.stars are formed when clouds of dust which contain hydrogen and helium.the central gravity attracts and the cloud collapses in itself.this continuous collapsing causes heat thru friction and a star is formed.in a planet there is heat,but not enough,i.e,a star has more mass than a planet.this affects the gravity and there fore a molten core is formed in the centre.it may be confusing to know which one is a star and which one a planet with your naked eye.but planets are USUALLY brighter than stars.you need a powerful telescope to tell a star from a planet.

Answer 7

Stars and planets are very different kinds of objects. You need to start over with some basic information. Discuss this with your teacher.

When you look at the night sky, the points of light you see include stars, planets, and other objects. But you see hundreds of stars for every one planet, nebula, galaxy, cluster, or other luminous objects.

Answer 8

No, stars are really stars. But the bright planets in our solar system (Mercury, Venus, Mars, Jupiter, and Saturn) look like stars to the naked eye.

Currently you can see Venus and Saturn in the evening sky, and, if you look at the right time, Mercury. Venus is the very bright "star" in the western sky after sunset, and Saturn is the bright, yellowish extra "star" in the constellation Leo.

Answer 9

When you look up in the sky at night you see stars. Most of them are suns in other solar systems. Some of them are planets. Venus, Mars, and Jupiter are pretty easy to find when they are in the right alignment. Some of these stars are other galaxies. Some are nebula.

When you look at the stars you are seeing a lot of different things.

Answer 10

Stars are like our sun ,and so very bright that u cant see planets that might be there.
