Galileo Galilei of the 21st century is an unknown man who has discovered more moons than no one is going to discover

If they asked you about an astronomer, you would probably think of Copernicus or Galileo Galilei. Maybe Carl Sagan came to mind. If they add “to be alive,” you might answer Neil Degrasse Tyson or, in the event that you are a fan of Queen, Brian May. The name that would hardly come out in the conversation is Scott S. Sheppard, an astronomer as prolific as unknown.

The number 1 in yours. Yeah Cristiano Ronaldo He is the greatest scorer in the history of professional football, Scott S. Sheppard is the CR7 to discover objects in our solar system. In total, he has put his name in more than 200 planetary moons: 78 of Jupiter, 119 of Saturn, three from Uranus and three of Neptune.

Practically half of all known planetary moons. A record that, as points out Iflscienceprobably will never be overcome, and he has continued to swell it in recent months.

The true king of Jupiter. In April, the International Astronomical Union (IAU) confirmed the discovery of two new moons in Jupiter, raising the official total giant to 97. Their provisional names are S/2017 J 11 and S/2017 J 10. Both are small moons and with retrograde orbits, that is, they revolve in the opposite direction to the rotation of the planet, something common in the outer and smaller satellites of Jupiter.

And yes, he has discovered them Scott S. Sheppardthat with these two new findings, he adds almost 80 moons of Jupiter to his credit. To put it in perspective: Galileo discovered the first and largest moons of Jupiter in 1610. Since 2000, Sheppard has overwhelmingly dominated the search for Jovian satellites.

What is resisting: Planet 9. He extensive curriculum Sheppard looks more like the index of an astronomical atlas than to the discoveries of a single person. In addition to natural satellites in Jupiter, Saturn, Uranus and Neptunethis astronomer of the Carnegie Institution for Science in Washington DC has also discovered 23 minor planets, six candidates for dwarf planets, three comets that bear their name (Sheppard – Trujillo, Sheppard – Tholen and Trujillo – Sheppard) and The most distant object ever observed In the Solar System: 2018 Ag37 “Farfarout”, about 130 times the distance between Earth and the Sun.

This is where your work becomes even more fascinating. Many of his discoveries are transneptunian objects such as 541132 Leleākūhonua “The Goblin”. And it is no accident. Sheppard and his colleague Chadwick Trujillo found them while looking for something much bigger: The hypothetical planet nine. Themselves proposed in 2014 The existence of a superstraier -type distant planet to explain the strange orbits grouped from objects such as the Minor Sedna planet.
