Interstellar clouds (..nebulae..) have extremely low densities; they're little more dense than empty space. About the only effects our solar system might notice, particularly Earth, is that global temperatures would decrease slightly. Many astronomers believe that Earth has gone through such clouds in the past, and will do so again. They think that ice ages might be caused by such passages.

Not a lot. Interstellar means in the space between stars. We are right next to a star so the cloud wouldn't be interstallar any more.
Some of the dust in such a cloud would be swept up by the planets and the rest would be blown out back into interstellar space by the solar wind. There is a shock wave way past Pluto where deep space collides with the solar wind and is where I reckon interstellar space starts.

In fact; were are already in one. Our Solar System is in the middle of a huge cloud that has billions and maybe trillions of asteroid at edge. It is called the Oort Cloud. The Solar System was born when a supernova occurred. When the Sun became a star, its solar wind pushed all the gases and dust into space. But these gases form a surround circle around us and created the Oort Cloud.
This information seems unfamiliar, but it's true.

Interstellar area isn't uniform. It is composed of areas of better and decrease density, magnetic field potential, cosmic ray intensity and so on. those areas have a tendency to be super, on the size of light years, and for this reason take thousands and thousands of years for th photograph voltaic gadget to traverse. it would look not likely that our photograph voltaic gadget might at any time be not moving from or into some area or yet another. In cosmic words, an "potential cloud" mihgt recommend an far greater than a pair of Joules of potential in step with million cubic miles. this may be very interesting to expert astronomers, yet not often some thing that would have any consequence on our planet that anybody else will notice. Cheers!

I have to agree with the people who say not much. The densest interstellar cloud is about a quadrillion times less dense than the air on Earth. That is REALLY thin.

The old professor says: The solar wind from our own sun produces a denser medium than the average nebula. Not to worry...our solar system was born in the midst of a type of nebula called a stellar nursery, along with a bunch of sibling stars.

I recall hearing a couple yrs ago that there is evidence that we are now engulfed. Worth looking up

They are so defuse that nothing would happen

It would be curtains for most if not all of us.
