Yes, it has a mass - though the mass is quite small. As far as I know, the neutrino has not been found to have smaller parts.
The tau neutrino has mass and is denoted with the symbol μ.
The tiny subatomic particle related to the electron that has no electric charge and little mass is the neutrino. Neutrinos are extremely difficult to detect due to their neutral charge and low interaction with matter.
For now, no particle has a mass less than zero. The Electron Neutrino for example has a mass of 0.0000079 eV (Or something like that). And the Charm quark has a mass of 1.29 GeV. Maybe you mistook it with spin or charge?
The smallest particle is the muon neutrino. The subatomic particles are not measured in size; they are measured in energy. The muon neutrino has an energy of less than 0.170 MeV/c2.
IceCube is a particle dectector located at the South Pole and it records the massless sub-atomic particle Neutrino. IceCube is the largest Neutrino detector.

Neutrinos, but their mass is very, very small.
A photon is a unit of light and has a mass of 0 where is a Neutrino has a small but nonzero mass. Neutrino's are similar to electrons in most regards, except neutrino's have no charge. Where photon's travel at the speed of light neutrino's come close but do not.
The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.
A neutrino is an elementary particle and is considered to be nearly massless. Their rest mass is still not well determined, but it is known to be very small, less than 0.12 eV. In comparison, the mass of an electron is about 511,000 eV.
The solar neutrino problem relates to the discrepancy between the proportions of the different flavours of neutrinos emitted by the sun in the theoretical model as opposed to experimental measurements. Whilst the sun primarily emitts electron neutrinos, neutrino observatories such as SNO+ detected neutrinos in roughly equal proportions of the three flavours; furthermore the quantity of electron neutrinos detected was less than the theoretically predicted value. Both of these can be explained by neutrino oscillation - in which the neutrinos alter their mass to change their flavour (ie. an electron neutrinos gain mass to change to a muon neutrino). This would also explain the relative lack of electron neutrinos, thus solving the solar neutrino problem!
An antineutrino is the antimatter counterpart to a neutrino. It has no electric charge, very low mass, and interacts very weakly with matter. Antineutrinos are produced in nuclear reactions, such as in the Sun or nuclear reactors.
Units of measurement aren't made up of anything. The smallest unit of measurement is the Plank unit - 10^-35m. The smallest sub atomic particle is a Neutrino, and it is made up of, a Neutrino!
No. The smallest particle of matter appears to be the electron neutrino, with a mass somewhat less than 2.2 eV. Even the electron, at 511 eV, is massive, compared to the neutrino.
Three different types of neutrinos are recognized. The latest work on the subject suggests that the combined mass of one of each type adds up to less than one billionth of an AMU.
The speed of a neutrino is close to the speed of light. Neutrino's have different energies based on mass. There are three neutrinos each of varying mass and therefore of different energies. So, a Tao flavored neutrino has more mass than an electron flavored one giving it more energy, however due to relativity it will travel slower based on it's mass. This can happen because they have mass. In the case of a photon (i.e. a massless particle) the energy is based on electromagnetic frequencies, however this determines the way in which light gets scattered when it hits different mediums. Though most of this stuff is covered in most modern physics books and classes.
