Massive objects like the sun do deflect the paths of neutrinos, similar to how they affect photons, as both are influenced by the curvature of spacetime according to general relativity. Neutrinos possess a nonzero rest mass and travel at speeds close to, but not exactly at, the speed of light, which contributes to their interaction with gravity. The discussion emphasizes that all particles, regardless of their mass, are subject to gravitational deflection. This property of spacetime ensures that both light and neutrinos are affected by massive objects. Ultimately, the deflection of neutrinos by massive objects is consistent with the principles of general relativity.

TL;DR
Do massive objects deflect the trajectories of neutrinos?
We know the results of Einstein's experiment in 1919. Simply stated, the sun deflected the paths of photons. The results were exciting for many reasons--one of which was that photons have no mass. Neutrinos do have mass. Do other massive objects, such as the sun, deflect the paths of neutrinos?

Yes. Why would neutrinos be any different from any other massive particle in this regard?

Thank you for the rapid response Orodruin.

Don't Neutrinos have nonzero rest mass and still travel at lightspeed? Could this possibly give them the inertia needed to continue in a straight line, piercing stars and galaxies unbent as well as unslowed?
Doubtful, but do we know?
 
They typically travel at a speed very close to but below the speed of light. The difference is too small to measure it but it is there.
Everything is deflected by gravity. This is a property of spacetime, it doesn't depend on the particle type.

To your question, general relativity tells us that mass bends space-time. So light and neutrinos are deflected by massive objects.

Thread 'Some confusion with the Binding Energy graph of atoms'
My question is about the following graph: I keep on reading that fusing atoms up until Fe-56 doesn’t cost energy and only releases binding energy. However, I understood that fusing atoms also require energy to overcome the positive charges of the protons. Where does that energy go after fusion? Does it go into the mass of the newly fused atom, escape as heat or is the released binding energy shown in the graph actually the net energy after subtracting the required fusion energy? I...
Hello everyone, I am trying to calculate the energy loss and straggling of alpha particles with same energy, I used LISE++ to obtain the energy loss in every layer of the materials using Spectrometer Design of LISE++, but I can only calculate the energy-loss straggling layer by layer. Does anyone know the way to obtain the energy-loss straggling caused by every layer? Any help would be appreciated. J.
