Using a Tethered Asteroid as a Sun Umbrella to Mitigate Climate Change
A new study has suggested an innovative way to protect Earth from the Sun’s harmful radiation - an umbrella-like shield made of an asteroid tethered to a satellite. The idea, proposed by researchers from the University of Colorado Boulder, is to place the asteroid at a specific distance from the Earth known as the Lagrange Point 1 (L1), where the gravitational pull of the Earth and Sun are balanced. This would create a protective barrier between the two, blocking out some of the Sun’s radiation before it reaches the Earth. The idea is still in its early stages, but it could offer a unique solution to the problem of global warming.
