Midheaven
The highest point of the zodiac at your birth (MC). It speaks to career, ambition and reputation.
If the Ascendant is where the sky meets the eastern horizon, the Midheaven is the point directly overhead in the sky's path. It's marked MC (from the Latin medium coeli) at the top of the chart.
It describes the direction you're heading in public life: the work you want to be known for.
