Is it true that the Sun will expand over the four inner planets in a couple million years?
Not so fast!! 😉 Everything is ‘under control’ for the next 4 or 5 BILLION years–basically as long as the Sun has already been around–and then yes it will expand and its outer atmosphere will envelope the inner planets… ;-( MAGNETISM QUESTION: How does the magnetic field of the Sun change during its cycle? ANSWER: The Sun’s magnetic field goes from being relatively simple (like that of a bar magnet) at solar minimum to being very complex at solar maximum. It takes it about 11 years to go from solar max to solar min. You may have heard of this. It is also called the sunspot cycle because the number of sunspots increases as the Sun’s magnetic field gets more complex. NASA QUESTION: What do you know about NASA?
