- Also every month, the Moon will reach its minimum declination at 18 north or south.
- Consistently, equinoctial markers and alignments were made to an declination well over half a degree to the north.
- He also determined the latitude and longitude of many stars, and measured the greatest declination of the planet Mercury.
- It's easy enough to gauge an asteroid's longitude and latitude (ascension and declination in astro-speak), but figuring out its current celestial position is tricky.
- To calculate the distance we need to know the declination of the sun on a given day.
