Meteors of varying sizes hit the Earth ten thousand times a day. Most of them are the size of a grain or sand or smaller; some are as big as a grain of rice. A few are the size of a soccer ball.
And once in a while, something bigger hits. Every few years, something the size of a car hits the Earth; every few centuries, something the size of a house hits us. Every few million years, something the size of a mountain hits, causing massive devastation.
It WILL happen again, but we don't know when. Nothing particularly hazardous is currently on the radar.
There is a moderately large asteroid called "Apophis" which will make a close approach to Earth on Friday, April 13, 2029, but will certainly miss. It will be back seven years later, on Friday, April 13, 2036, when it will very probably miss. The difference between "certainly miss" and "very probably miss" causes NASA scientists some worry, but as they get a better and better track of Apophis, the odds of a collision are going down.
A meteor is a meteoroid that... burns up in Earth's atmosphere.

The earth and the sun always form a line. They are the end points of that line and therefore are always lined up.
When the Sun, Earth and Moon are lined up in such a way that the full moon moves into the Earth's shadow, it creates a lunar eclipse.

No, not a meteor shower. The dinosaurs became extinct after a meteor struck the earth which blocked out the sun and killed much of the vegetataion that the dinosaurs used for food.
The Earth's atmosphere is warm and as the meteor goes through it, it heats up and starts to burn, which is how we see them.
A meteor is a lump of rock in space. When one of these pieces of rock comes close to the earth it may burn up in the atmosphere as a shooting star. An earth grazing meteor is a meteor that has come close enough to our atmosphere that it starts to burn up, but will still pass us by as the angle is too shallow. It will go back out into space having been deflected by earths gravity.
