In 1766, Johann Daniel Titius of Wittenberg discovered a numerical progression that roughly matched the orbital distances of the known planets — Mercury through Saturn. In 1772, Johann Elert Bode of ...

Planet predictor A centuries-old idea about how planetary orbits are spaced in relation to the Sun is proving remarkably accurate in predicting the location of planets orbiting other stars, according ...

We take knowledge of the existence of asteroids (aka minor planets) for granted in our modern world. Ranging in size from boulders to hundreds of miles in diameter, tens of thousands of known ...

Illustration shows the habitable zone for different types of stars. The distance to the habitable zone is dependent on how big and bright the star is NASA, Kepler There could be billions of planets ...

Astronomers have discovered thousands of exoplanets using the Kepler satellite. By analyzing these planetary systems, researchers have calculated the probability for the number of stars that might ...

In 1800 a group of enthusiastic astronomers formed a Neighbourhood Watch to keep an eye on what was happening in the heavens. They were looking for a missing planet. No misappropriation of any ...

Twenty-three years ago, Walter Murch, A&S '65, became fascinated by the 17th-century astronomer Johannes Kepler through reading The Sleepwalkers, Arthur Koestler's 1959 history of Western cosmology.

We use three and half years of Kepler Long Cadence data to search for the 97 predicted planets of Bovaird & Lineweaver (2013) in 56 of the multi-planet systems, based on a general Titius-Bode relation ...
