Neutrinos can quasi fly through the entire universe without being influenced on their trajectory by planets. Read more:

Today I read an article which dealt with the maximum speed and there I found the following information about neutrinos:

 

It is about neutrinos. They carry no load and were theoretically predicted 1930 by the Austrian physicist Wolfgang Pauli. The reason being that otherwise energy would have gone lost with radioactive decay. That is why Pauli postulated the existence of a new particle, which hardly interacts with matter: neutrinos can quasi fly through the entire universe without being influenced on their trajectory by planets. About 60 thousand million neutrinos, which came into being with nuclear reaction in the Sun, reach earth for instance every second and per square centimetre.

Most of them simply fly through. Only about a dozen collide with an atom and can be measured. That succeeded under great expense for the first time 1956. Though only a third of the predicted neutrinos were ascertained at that time. The explanation was that there are not just one kind of neutrinos but even three. And these three kinds can also still change into one another all the time. Something that one calls neutrino oscillation.
