Astronomer names minor planet after B.C. First Nation

CENTRAL SAANICH, B.C. — When Tsawout First Nation Chief Harvey Underwood looks up at the stars, he knows his community has a place among them.

That’s because floating in the asteroid belt between Mars and Jupiter is a newly discovered minor planet that bears his community’s name.

“Our name means, ‘houses on the hill.’ Now our planet is ‘houses in the universe,’ I guess,” said Underwood from his home on Vancouver Island. “It’s mixed in there with all the stars.”

Astronomer David Balam presented a plaque to the First Nation marking the naming of the asteroid Tsawout at a meeting of the International Astronomical Union in Victoria last week.

Balam said he discovered the two-kilometre-wide astronomical object in 2007.

But he said the official process for naming takes between five and 20 years, and involves intricate mapping of the minor planet’s orbit. It also requires approval from both the union and the Minor Planet Centre, a worldwide organization in charge of collecting and publishing observational data for minor planets.

Minor planets, or asteroids, are chunks of rock left over from the formation of the solar system, Balam said. Tsawout is one among millions orbiting in the asteroid belt.

Balam said he spends a lot of his time on a telescope at the observatory on Little Saanich Mountain.

“This isn’t, how old is the universe and where do we come from. It’s a bit more fundamental. It is: Is that thing going to hit the Earth?” Balam said.

Balam said Tsawout is the 49th minor planet he has named. Others bear the names of Canadian astronomers, institutions — including his alma mater, the University of Victoria — and people in his life.
