how can a star fall?

Question

i dont know anything about falling stars. but if there is no gravity in space how can is a shooting star exist?

Answer 1

In space is gravity anywhere! The earth attracts an object always. It does not the matter how far.. However on the surface of the earth it is maximal and the more far the object is, the fainter the gravitational attraction.
The earth seems to work as a vacuum cleaner. It attracts anything! Including rocks. If they fall through the air they become very hot en start to to glow. That is a 'falling star', so no star at all!

Answer 2

Star doesn't fall.

For bodies with a size scale larger than the atmospheric mean free path (10 cm to several meters) the visibility is due to the heat produced by the ram pressure (not friction, as is commonly assumed) of atmospheric entry. Since the majority of meteors are from small sand-grain size meteoroid bodies, most visible signatures are caused by electron relaxation following the individual collisions between vaporized meteor atoms and atmospheric constituents.
A very bright meteor may be called a fireball or bolide. The International Meteor Organisation defines fireballs as being meteors of magnitude -3 or brighter. The meteor section of the British Astronomical Association on the other hand has a much stricter definition, requiring the meteor to be magnitude -5 or brighter.
A meteor is a meteoroid that has entered the earth's atmosphere. It will then become brightly visible due to the heat produced by the ram pressure. If a meteor survives its transit of the atmosphere to come to rest on the Earth's surface, the resulting object is called a meteorite. A meteor striking the Earth or other object may produce an impact crater.
The velocities of meteoroids entering the earth's atmosphere vary from a minimum of about 11.2 km/sec to the 71 km/sec velocities of the Leonids. Meteors with even higher velocities are believed to be inter-stellar in origin.[1]
Molten terrestrial material "splashed" from such a crater can cool and solidify into an object known as a tektite.
Meteor dust particles left by falling meteoroids can persist in the atmosphere for up to several months. These particles might affect climate, both by scattering electromagnetic radiation and by catalyzing chemical reactions in the upper atmosphere.

The centre dot is an Asteroid being followed by the sequence; the object that flashes by near the end is a meteor.
A meteor is the visible path of a meteoroid that enters the Earth's (or another body's) atmosphere, commonly called a shooting star or falling star.

Answer 3

Shooting stars are mostly grit from space colliding at very high speed with air molecules high up in the sky.

As Earth travels in its orbit around the sun it runs into clouds of grit generally pulverized rock that also orbits the sun. Many shooting stars are produced by grit no larger than a grain of sand. Some of the more spectacular ones are pea-sized and the really stunning (but very rare) fireballs are the size of an orange or larger. These objects collide with air molecules some 60 miles (95 kilometers) above Earth's surface and, due to their very high speed, they begin to glow white hot. We see a streak of light as they burn up. The scientific name is meteor but shooting star will do fine (just tell the kids that they are not really stars).

Answer 4

Shooting stars are rocky debris that collide into Earth's atmosphere, so they heat up and burn up.

Stars do not "fall." Falling is something relative to where you are, really. On Earth things fall to the ground. In space nothing falls, unless you are near an object with gravity.

Answer 5

A shooting star is a totally different phenomina than you think it is I think.

A "falling star" is categorized by any kind of space rock or space debris entering the earth's atmosphere. They cut the atmosphere at an angle, and therefore you see the bright trail in the sky as it burns up. It is also refered to as a "meteor shower".

When you see a trail that appears to be much larger than others, chances are that the rock (or debris) has just cut the atmosphere at a much sharper angle, therefore leaving a "longer" or "wider" tail.

Answer 6

A "star can't fall....a shooting star is a meteor; a small piece of space debris burning up in the earths atmosphere.

Answer 7

A shooting star is not actually a star, but a meteorite. It's a small object that burns brightly as it enters the atmosphere and falls to earth.

Answer 8

The earth attracts objects from space that burn in the atmosphere and resemble stars. There is gravity in space, but almost a complete vacuum (the absence of matter).

Answer 9

Gravity exists in space.
Shooting stars are meteors burning up in Earth's atmosphere. The name is from the appearance and from when they didn't know any better.

Answer 10

its a nickname for a meteorite falling to earth
its not actually a star but a meteor before it falls and after breaking up hitting the atmosphere a meteorite a space rock
showers happen all the time and are recorded shold check around for some vids
