There is this wonderful search engine, Google, that has the answer to all your questions.

Stop trolling Astronomy and Space.

Neutrinos are a family of six fundamental particles (3 particles and three anti-particles) which are believed to have a very very small mass. Originally they were thought to have a zero rest-mass, but current theory requires that they have some mass which enables them to oscillate into one another.
They travel at close to the speed of light (if they are massless they would travel at the speed of light) and have no electrical charge. In fact they interact very little with matter.
They are fundamental particles, part of the basic set of tinker-toys that the universe is made up of.
