Yes. Yes. And: if it wasn't, it would attract opposite charge until it was.Quantum River said:Is the Solar system electro-neutral?

The Earth is considered electro-neutral because it has an equal number of positive and negative charges overall. This is due to the fact that the Earth is made up of both positively charged protons and negatively charged electrons in equal amounts, resulting in a net neutral charge.
The Earth maintains its electro-neutrality through a process known as charge conservation. This means that for every positive charge created or added to the Earth, an equal amount of negative charge is also created or added to balance it out.
The electro-neutrality of the Earth is significant because it allows for stability and balance in the Earth's electromagnetic field, which is necessary for supporting life. It also allows for the Earth to interact with other celestial bodies and cosmic radiation without being drastically affected by their charges.
Yes, the Earth's electro-neutrality can change in certain circumstances. For example, during a thunderstorm, the Earth's electro-neutrality can be temporarily disrupted due to the buildup of positive charge on the Earth's surface. However, this is usually balanced out by lightning strikes, which equalize the charge and restore the Earth's electro-neutrality.
The Earth's electro-neutrality is measured using a unit called the Coulomb, which represents the amount of electric charge in a system. The net charge of the Earth is typically measured in coulombs, with a value close to zero indicating its electro-neutrality.
