Was a Great Conjunction the Christmas Star?

Episode notes from The Ten Minute Bible Hour

Could the Christmas Star described in Matthew 2 have been a great conjunction of Jupiter and Saturn? Those two planets align about every twenty years, but once or twice a millennium they align so closely that they appear as one incredibly bright temporary object that’s highly visible to the unaided human eye. This happened in December 2020, March of 1226, and in May of 7 BC. In this video we’ll look at the historical and astronomical evidence as we think through four different possibilities for what the Christmas Star might have been.

Novae are relatively small explosions in double star systems. They come about when a white dwarf’s intense gravity tugs material away from a companion star. Gas piles up around the white dwarf and eventually becomes dense enough to ignite in a burst of nuclear fusion.
Most supernovas, meanwhile, mark the deaths of massive stars and the formation of neutron stars. They are triggered when a shockwave tears through the outer layers of a dying star, igniting a firestorm of nuclear fusion.

As a result of their long orbits, Jupiter and Saturn meet in the sky only once every 20 years. In this period of time, Saturn completes two-thirds of its 30-year orbit (since 20 is two-thirds of 30). In the same period, Jupiter completes one 12-year orbit, plus, in the remaining 8 years, two-thirds of its next orbit (since 8 is two-thirds of 12). In other words, 20 years is the time it takes Jupiter to catch up and pass Saturn again as they circle the Sun.
The above figures are round numbers. More precise figures are 11.86 years for Jupiter’s orbital period, 29.46 years for Saturn’s orbital period, and 19.86 years for the average frequency of a great conjunction
