Solar System's Engine

The Sun is not just a light source — it is the gravitational anchor holding eight planets, dozens of dwarf planets, and billions of smaller objects in orbit. Its gravity reaches far beyond Pluto, keeping the distant Oort Cloud tethered at nearly a light-year away.

The Sun also drives space weather throughout the solar system. Its magnetic field flips polarity every 11 years, creating cycles of heightened and reduced activity. Understanding our star is essential for protecting the technology civilization depends on.
