Mercury
Measured
Innermost planet. MESSENGER mapped it. The 42s are rooms, not the planet’s name.
The messenger planet. A thin silicate shell near 420 km. On 20 April 1971 the table prints speed −0°42′ per day. Tesla’s incorporation morning, Mercury at 4°20′ Cancer. Mariner 2 and Mariner 10 are Venus rooms. They do not live here.
What it supports
IAU planet Mercury. NASA facts. Hauck 2013 outer shell 420 ± 30 km. Astro-Seek 1971 cycle, 20 April, −0°42′/d. This card is the world those rooms belong to. Messenger and planetai keep the site.
What it does not
Not 42. Not Mariner 2’s 42-minute Venus scan. Not Mariner 10’s S-band 42 km at Venus. Not Tesla. The planet is not the Answer.
