What is the average speed of a shooting star
Shooting stars are extremely fast, reaching speeds of over , miles per hour! The temperature of a shooting star is around 3, degrees Fahrenheit. Explanation: Despite its name, shooting stars are not actually stars. Shooting star is either a piece of a small rock or dust from space that heats up when is enters the Earth's atmosphere. Shooting stars are basically meteors. A shooting star is a small piece of rock or dust that travels through the earth's atmosphere.
These are known as meteoroids. They glow is because of the speed at which they move through the atmosphere. Meteor is the trail of light that is produced during the burning. The pass of asteroid Apophis. The April 13, , encounter of Apophis with Earth will be extremely close.
That's very close for a space rock over 1, ft meters across! The asteroid is thought to have been between 10 and 15 kilometres wide , but the velocity of its collision caused the creation of a much larger crater, kilometres in diameter - the second-largest crater on the planet.
We believe anything larger than one to two kilometers one kilometer is a little more than one-half mile could have worldwide effects. There has only been one recorded, known time that someone has ever been hit by a meteorite. A lady called Ann Hodges was hit by a meteorite n November 30, , whilst she was having a nap at home. It is commonly called the Hodges meteorite because a fragment of it struck Ann Elizabeth Fowler Hodges — It is estimated that probably meteorites reach the surface of the Earth each year, but less than 10 are recovered.
This is because most fall into the ocean, land in remote areas of the Earth, land in places that are not easily accessible, or are just not seen to fall fall during the day. On any given night, depending on our luck, we can see between one and two shooting stars per hour ; but on certain dates they occur much more frequently and many more can be seen: when this happens we call it a meteor shower.
A meteor shower is a bunch of pieces of a comet that have been left behind or broke off the comet. When the Earth passes through this field of debris, the pieces burn up in the atmosphere.
The American Meteor Society offers a calendar so that you can plan your observation days. Falling Shooting Stars Facts.

Meteor showers are also called swarms. Witnesses saw a giant fireball in the afternoon that some said was brighter than the sun. The meteorite was found buried 10 feet 3 meters deep in the ground. It weighed 2, lbs. The most famous meteorite crater in the United States is misnamed Meteor Crater. It's in Arizona, and it's huge.
The rim rises feet 45 m from the surrounding plain, and the hole is feet m deep and nearly a mile wide. It was the first crater that was proven to be caused by a meteorite impact, which occurred between 20, and 50, years ago. Meteors are often seen falling from the sky alone — one here, one there. But there are certain times in a year when dozens or even hundreds of meteors per hour will light up the sky, seemingly coming from one part of the sky, radiating in all directions, and falling toward Earth one after the other.
There are several periodic meteor showers that astronomers and amateur observers wait for every year. Meteor showers are named after the constellations from where the shower appears to be coming from. For example, the Orionids appear to originate from the mighty Orion constellation, while Perseid meteors seem to be coming from the Perseus constellation.
Leonids: The brightest and most impressive is the Leonid meteor shower , which can produce a meteor storm that showers the sky with thousands of meteors per minute at its peak.
In fact, the term "meteor shower" was coined after astronomers' observed one of Leonids' most impressive displays in The Leonids occur every November, but the shower's most beautiful display happens at intervals of about 33 years, with the last one lighting Earth's sky in ; it is not expected to be repeated until Related: Amazing Leonid meteor shower photos. Perseids: Another shower that is worth keeping awake for is the Perseid meteor shower , which is associated with the Comet Swift-Tuttle , which takes years to orbit the sun.
Earth passes through the comet's orbit during the month of August every year. It is not as active as the Leonids, but it is the most widely watched meteor shower of the year, peaking on Aug. Orionids: The Orionid meteor shower produces meteors from Halley's comet , which orbits the sun every 75 to 76 years.
The Orionid shower happens every October and can last for a week, treating patient observers to a show of 50 to 70 shooting stars per hour at its peak. Related: Orionid meteor shower sparks bright fireballs video.
Quadrantids: The Quadrantid meteor shower comes from the debris of an asteroid called EH1, which some astronomers think was part of a comet that broke apart centuries ago. The debris enters Earth's atmosphere in early January and offers astronomers and other observers a brief show. Related: Spectacular Quadrantid meteor photos. Geminids: Like the Quadrantids, the Geminid meteor shower also came from dust particles of an asteroid, this time a near-earth asteroid called Phaeton.
Meteor showers are mostly from comets, so having an asteroid as parents make the Quadrantids and Geminids different from other meteor showers. The Geminids happen in December and spray up to 40 meteors per hour out of the Gemini constellation at its peak. Other meteor showers to watch out for are the Eta Aquarids , also remnants of Halley's comet, in May; and the Lyrids , which have been chronicled for more than 2, years, in late April. People living in the Northern Hemisphere are in the best position to observe the most beautiful meteor showers.
