The density of the solar wind can be neglected in the calculation of the solar wind dynamics because Maxwell equations are sufficient

Electromagnetic perturbations originated from solar flares can reach the Earth in less than 10 minutes and interfere with our tele-communications

The coronal mass ejections can reach the Earth in less than 10 minutes and create auroras, which modify the ionosphere and therefore the tele-communications

The cosmic rays coming from the Sun can modify the DNA of the communication devices

1 atm, as the pressure does not change a lot at such low altitudes

It depends greatly on the time of the day. It can change of 1 order of magnitude between day and night, due to the pressure of the solar wind

necessary, as they are essential for diagnostics like magnetic resonance imaging in medicine

necessary, as without them, the cosmic rays would destroy the planets

very important for sustaining life, as they protect the living beings from the extraplanetary ionic radiation

There are no protons due to the action of the cosmic rays.

The equatorial coordinates are much easier to calculate as they only depend on measurement with respect to the horizon

The equatorial coordinates do not change when the sky rotates, and therefore the equatorial coordinates of a star do not change when observing the sky from different planets of the solar system

The equatorial coordinates of a star do not change when observing the sky at different latitudes on Earth
