Zoozve: how a typo on a kids's poster turned the primary 'moon' of Venus | Science | EUROtoday
The International Astronomical Union has simply named Zoozve the primary quasi-moon found on a planet within the Solar System, a routine choice for that group representing the astronomical world, which is devoted to naming and renaming all of the celestial our bodies by the dozen. However, Zoozve's story has a number of peculiarities that make it an distinctive case. A father's curiosity has ended within the firmament, a nice serendipity arising from a mistake. And it began in a toddler's room when it was time to tuck him into the sheets.
A yr in the past, Latif Nasser, co-host of the scientific podcast Radiolab, was making ready to place his son to mattress when he observed a element on the poster of planets he had in his room. Nasser, with a doctorate in History of Science from Harvard, was struck by seeing in that drawing an area physique with a wierd title. “Venus had a moon called Zoozve. “I had never heard of her,” remember now Nasser in a thread on the social network X. He Googled and confirmed, paradoxically, that Venus has no known moon. It is, along with Mercury, the only planet without natural satellites in the Solar System. The word “Zoozve” additionally didn’t return ends in the major search engines.
So I known as the illustrator, a Brit named Alex Foster. (He does have a canine, however it’s named Winnie.) He didn’t know a lot about astronomy however he swore he didn’t make it up. He mentioned he discovered it on a giant record of all of the moons on-line. I believed him, however couldn’t discover the record. pic.twitter.com/kwCWWwBq0t

So Nasser ended up calling Alex Foster, the illustrator who had drawn the poster. Foster swore that he had not made it up, that he had taken it from a scientific record of moons. A pal of Nasser's who had labored at NASA discovered the important thing: it was a typo, the cartoonist had made a mistake when transcribing that title. It was not ZOOZVE, however 2002-VE, a reputation that corresponds to that of an area rock noticed round Venus in 2002. More particularly, its title is 2002-VE68, and it’s an asteroid about 250 meters broad. And it’s not a moon of Venus, as a result of it doesn’t have one. “But it is also NOT a moon of Venus. It is both and neither,” explains Nasser enigmatic.
It is a quasi-moon, an area object that really orbits a star, however does so with a rhythm and stability that makes it seem that it orbits a planet. Thanks to this resonance across the two our bodies, quasi-moons can accompany a planet for a very long time earlier than escaping its affect. In 2010, Zoozve approached Earth and allowed us to raised analyze the rhythmic dance that it maintains with Venus. Spanish astronomers Carlos and Raúl de la Fuente confirmed that 2002-VE68 will abandon its present standing as venusian ruler in a comparatively brief interval: about 500 years. And they calculated that it entered this uncommon dynamic state after an in depth encounter with Earth greater than 7,000 years in the past.
“With the enormous number of smaller bodies (asteroids) that exist in the solar system, it is evident that sooner or later more than one will fall into the networks of the gravitational attraction of the planets,” says Javier Armentia, astrophysicist and director of the Planetarium of Pamplona. The astronomer explains that the Earth additionally has quasi-satellites, the primary found in 2010 and known as 2010 Tk7. Another terrestrial quasi-moon, known as Kamo'oalewa, was confirmed final yr. “They are gravitational resonances, that dance of planets carried by gravity. With more observations and better analysis, more precise celestial mechanics calculations are also emerging, which look at all the details and allow us to discover that sometimes the planets trap these bodies in orbits that resemble what they do with the real Moon. So we can call them moons or quasi-moons,” explains Armentia.
For this popularizer, the Zoozve case exhibits how a lot stays to be found and understood about our planetary surroundings, and the way even a mistake can lead us to study extra in regards to the universe. “As we know more and more about the Solar System, we are also finding things that we did not think were possible. We tend to think that the Earth already has its Moon and that's it,” he factors out. Zoozve's story due to this fact additionally displays the evolution of statement and evaluation methods in astronomy from its preliminary discovery in 2002 to its appointment in 2024.
Among the celestial our bodies named or renamed by the International Astronomical Union (IAU) in its newest bulletin (PDF) are additionally Incamajorca —as a result of the astronomer who found it’s from the Majorcan city of Inca— and Smurf, as a result of “In Puerto Rico, the word smurf is also used as an affectionate nickname.” The Union has lately promoted unique names and names of widespread and ancestral cultures, however it doesn’t all the time make such nice choices: in 2020, it needed to withdraw the title of two craters on the Moon as a result of they corresponded to 2 physicists with a notable Nazi previous.
The IAU describes the naming of Zoozve, “the first identified quasi-satellite of a major planet (Venus)” as follows: “When artist Alex Foster drew this object on a children's poster of the solar system, he mistook the initial characters of the provisional designation for letters , thus coining a strange and memorable nickname. Name suggested by Latif Nasser.” The promoter of the title has celebrated it on his podcast and on the networks: “They named him! Starting today, the first quasi-moon discovered in the universe is officially called Zoozve!” This story, which remembers how the universe remains to be filled with mysteries ready to be found due to human curiosity, can now grow to be a stupendous fable to learn earlier than tucking the kids into mattress and studying astronomy by wanting on the map of the planets.
