xVVGk Of all the bodies in our solar system, the sun is probably the one we want to give the widest berth. It gushes radiation, and even though its surface is the coolest part of the star, it burns at about 9,940°F, hot enough to incinerate just about any material. As such, there are no plans to send a manned mission in its direction anytime soon (Mars is much more interesting, anyway), but it can't hurt to figure out at what distance a person would want to turn back. You can get surprisingly close. The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up.
nWJVb TIL that during WWII, the British government implemented Operation Pied Piper, evacuating over 3 million children from cities to rural areas to protect them from bombings. These "evacuees" were sent away from their families, impacting communities but ensuring their safety.
