A neutron star that rotates rapidly and gives off pulse is call a pulsar.
a pulsar
Magma that reaches the Earth's surface is known as lava.
it change the earth atmosphere when magma flashes out then the earth surface will be dusty
The molten material that reaches earth's surface is lava :)
Magma that reaches the Earth's surface is known as lava.
Lava cools down and accumulates into rock as it reaches Earth's surface

It reaches earth as an electromagnetic wave.
A neutron star is unimaginably dense. It contains the mass of the Sun, but has that mass squeezed into a ball perhaps 20km (12 1/2 miles) across. Further, neutron stars are so small that they can spin very rapidly, many times per second or faster. When they spin they emit electromagnetic radiation which can appear as flashes from earth. If the magnetic pole of the neutron star is "pointed" [See related link - Pictorial of pulsar] towards Earth, they are called pulsars, as they "pulse" as they spin and can be detected. The flashes produced by the pulsars are detected as the electro magnetic radio waves caught up by the radio telescopes
When a meteor reaches the Earth's surface, it is classified as a meteorite.
No

The energy that reaches the Earth from the sun is known as sunlight.

If you mean in the same volume, only a tiny fraction of Earth - the neutron star is much smaller. The radius of a typical neutron star is perhaps 12 kilometers. In comparison, the Earth has a radius of about 6371 kilometers - that makes Earth's volume about 150 million times greater. (On the other hand, the neutron star has a much greater mass than Earth.)
No. The closest neutron star is over 434 light years away.
It is extremely unlikely that a neutron star (or any star or planet) will collide with the Earth, so this is not something that you need to worry about, however, if a neutron star were to collide with the Earth, the Earth would be captured by the intense gravitational field of the neutron star, and would be absorbed by the star. Under sufficient pressure, electrons and protons will merge to form neutrons, and so the atomic matter of which the Earth is composed can be converted into pure neutrons.
