It takes 55 times more energy to go to Sun than Mars: NASA
The Parker Solar Probe, launched on Sunday, will require 55 times more energy to 'touch' the Sun compared to a mission towards Mars, as per NASA. It will need to cancel sideways motion of the Earth, which orbits the Sun at over one lakh kmph. While doing so, it will become the fastest-ever man-made object, clocking nearly 7 lakh kmph.
