Answer the following about NASA’s 2023 discovery of six exoplanets orbiting the star HD110067, for 10 points each.
[10m] They were observed by NASA’s “Exoplanet Survey Satellite” that detects these events to discover exoplanets. These events involve a body passing in front of a star without obscuring it, unlike an eclipse.
ANSWER: transits [accept Transit Exoplanet Survey Satellite]
[10e] The exoplanets are located in the constellation Coma Berenices at a distance where this phenomenon would take about 100 years to reach Earth. This phenomenon is transmitted by photons.
ANSWER: light [accept light-years]
[10h] The six exoplanets unusually exhibit this phenomenon, in which their orbital periods are simple integer ratios with each other. The orbits of Io, Europa, and Ganymede exhibit the 4-to-2-to-1 form of this phenomenon.
ANSWER: orbital resonance
