    yes mercury.one reason is its high temperature being the nearest to the sun.other reason is the high concentration and pressure of gaseous elements.for the later reason the planet can not be seen by any orbital sat or any lander or rover.orbitals are prevented by near zero visibility and rovers or landers are crushed due to high pressure before they could land.
