Sunlight is one of the most important natural resources on Earth.
For any date and any place on Earth, this calculator returns sunrise, sunset, solar noon and day length from four inputs: date, latitude, longitude and UTC offset.
How far away is a galaxy whose light arrives stretched by a known redshift?
Kepler’s third law links three quantities: how far an object orbits, how long one orbit takes, and how massive the central body is.
Type a star’s parallax angle in arcseconds and this calculator returns its distance in light-years, with the parsec figure shown as a reading underneath.
Light in a vacuum always travels at exactly 299,792,458 meters per second, which makes it the universe’s most reliable ruler: at that speed, time and distance are two labels for the same quantity.
How far away is that star?
Convert any mass in kilograms into solar masses, the unit astronomers actually quote for stars, black holes and galaxies.
Give this calculator a planet’s radius and its average density and it returns the planet’s total mass in kilograms, with an Earth-mass reading so you can feel the scale instantly.
