  1. stars dont fall. shooting stars are meteors that fall to earth, not stars.

    our sun is a star. every star in the sky is just like our sun, only much much further away. each star is millions of times larger and more massive than the earth. so besides the fact that there are no stars in the immediate vicinity of earth, stars wouldnt fall to earth, the earth would fall into the star.


  2. The term "falling star" is a misnomer. The astronomical phenomena we usually call a falling star is actually a meterorite. A meteorite is a natural object originating in outer space that survives an impact with the Earth's surface. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting star.

    Most meteorites disintegrate when entering the Earth's atmosphere. However, an estimated 500 meteorites ranging in size from marbles to basketballs or larger do reach the surface each year.Very large meteorites may strike the ground with a significant fraction of their cosmic velocity, leaving behind a hypervelocity impact crater.

  3. they fall at a speed of 3,145,156 miles per hour.

  4. If a star "fell" to Earth, it would be pretty hard.  We would be obiliterated (actually, we would be swallowed by the star without too much of a hiccup).  Keep in mind that most stars are millions of times the mass of the Earth.  Really, the Earth would be the one to "fall" into the star since there would be an incredible gravitational mismatch.

    I wouldn't worry too much about it though.  We are in a stable orbit around the nearest star (the Sun) and it would take millions of years for an undetected star on a collision course to even get here.  

    Worry more about undetected asteroids,  one the size of Mt Everest could put us in a world of hurt.

    Now, to consider what you were probably really asking, here is a quote from the included source about meteor velocities:

    "Earth orbital speed is 28.8km/s, orbital escape speed is the square root of two times this, 42.1km/s, and surface escape speed is 11.2km/s. The slowest meteor would be one that just catches up with the earth then "falls", 11.2 km/s. Don't expect anything less than 12km/s. But a retrograde body in parabolic orbit (the maximum speed for a body at a distance of 1AU that is a member of the solar system) might close with earth at a speed of 42.1+28.8=70.9km/s plus the 11.2 "fall" for a total of (total2=70.92+11.22) 72km/s. So we expect a range of 12-70km/s with the slower ones in the evening ("catch up" and prograde, no retrograde) and fast ones in the morning where we do the catching-up and collect all the retrograde rocks"

    Taking these atmospheric entry velocities, the final force (how hard) the meteor strikes the Earth's surface depends on whether the meteor is big enough to not burn up in the atmosphere, how much the atmosphere slows it down before it hits, and how much mass it has.  A massive meteor will hit harder than a tiny meteor.  

    My recommendation is that you don't try to catch it even if it is very small.
