An event will be held to observe the rendezvous of Venus and Jupiter.
Gwacheon National Science Museum (Director Jeong-mo Lee) announced on the 18th that it would hold a special observation meeting close to Venus and Jupiter for two days from the 30th to May 1st in collaboration with the National Astronomical Observatory of Land Jeongjeong, Yanggu-gun (Governor Jo In-muk). Various events such as telescope observation and campfire will be held.
The orbital periods of Venus and Jupiter are 7.5 months and 11.9 years, respectively. Due to this difference in orbital period, the two planets in the sky come closer regarding every 3 years and 3 months.
The orbits of the two planets have different inclinations, so even if they approach each other, they do not overlap. It’s regarding ‘facing’. In this proximity, the angular distance between Venus and Jupiter is only 0.2 degrees, so it is expected that the two planets will be almost visible to the naked eye. This close is the largest since July 1, 2015, and the next close is August 12, 2025.
To observe the proximity of Venus and Jupiter, it is good to have an open eastern sky, and it may be difficult to distinguish between Venus and Jupiter without special equipment. It is possible to distinguish between Venus and Jupiter only with binoculars, and with a general astronomical telescope, Jupiter, Jupiter’s four moons (Io, Europa, Ganymede, Callisto), and even Venus can be observed. If you lower the telescope’s magnification, you can see Venus, Jupiter and their moons all at once in one view of the telescope.
Gwacheon Science Museum and National Astronomical Observatory are scheduled to hold a lecture on the secrets of shooting the Milky Way, and a campfire on the evening of the 30th, by Park Dae-young, head of the Gwacheon Science Center Astronomy and Space Team. The plan is to observe representative celestial bodies in spring with the 800mm main telescope and auxiliary telescope of the National Observatory, and to give small telescopes to campers for free observation. At dawn the next day, you will be given time to observe and photograph the Milky Way.
Dr. Jo Jae-il of Gwacheon Science Museum, who planned this event, hoped, “I hope that it will be a time to heal a little bit by observing the Milky Way, Venus, and Jupiter while camping physically and mentally exhausted from COVID-19 for a long time.”
For more information regarding the event, such as camping site reservations, from 9 am on the 19th. Gwacheon Science Museum websitecan be checked through
