Fun fact: The escape velocity needed to leave Earth’s gravity pull is 11.2 km/sec (7 miles/sec). At Earth, the escape velocity needed to leave the solar system is 42.1 km/sec (26 miles/sec). A marathon every second? I find this alarming.
I can’t help but wonder if the Roadrunner from Looney Tunes could escape Earth’s gravity. Can anyone find figures on The Roadrunner’s estimated top speed?
