Pelletier scientists estimate that Ultima Thule is Washington D.C.
"It is expected to be 30 km in diameter today," Pelletier said. "We suspect that it will not be spherical, it will have a curious shape like this, it will be a binary asteroid in a touch or close formation of two objects."
What has the question of Québécoen's birth to question even more? In fact, the signal of the Earth takes six hours to reach the spacecraft and return another six hours.
"So we must take into account the maneuver planning summits and updates," said Pelletier.
The New Horizons spacecraft came out on January 19, 2006, when Pluto was passing through, and from 2015 onwards he went into space. Johns Hopkins University Laboratory Applied Laboratory Laurel, Md., Non Pelletier and his team are working.
Ultima Thule was detected for the first time in 2014 using the Hubble Space Telescope, and after launching New Horizons they discovered a new rock.
NASA says scientists have hundreds of objects with a diameter of more than 30 kilometers in length, awaiting what is called the "third zone" of the solar system.
"I'm an explorer," Pelletier said. "I love spots (not explored) on the edge of the solar system. The Kuiper Belt was only found in the 1990s."
Until January 1, Pelletier will monitor Ultima Thule to celebrate its 44th birthday on Wednesday, December 28.
But his wife and two boys, ages 9 to 12, will go to Maryland to join in the coming days.
Pelletier worked on other space missions, when he traveled to space Saturnin Cassini and also attended Mars Curiosity.
