16:56Now PlayingA day is 24 hours, right? Right?!?! On this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice investigate the length of a day.
To start, Neil explains why a “sidereal day” is 23 hours, 56 minutes, and 4 seconds and a “solar day” is, on average, 24 hours. You’ll learn why Earth’s orbit around the sun impacts how we measure the length of the day. Should we re-define the length of a second? Discover more about leap seconds and how we decide when to add them to the calendar.
Find out more about atomic clocks and sun dials. Neil explains why the Earth is slowing down and why the Moon is spiraling away from us. We also discuss how tides serve as a counter-balance to the Earth’s rotation. All that, plus, we explore the many things that can impact Earth’s rotation including seasonal animal migrations, earthquakes, melting land glaciers, and more!
