91亚色-led research provides new insights on origin and evolution of asteroid Bennu

Friday October 9, 2020, TORONTO 鈥� Research published in , led by Lassonde School of Engineering Professor聽,聽provides new insights into the formation of near-Earth asteroid,聽Bennu, and how it evolved into its present shape.

Daly, the lead instrument scientist for Canada鈥檚 contribution of the OSIRIS-REx Laser Altimeter (OLA), and a team of researchers,聽used data from OLA to create a 20-centimetre resolution model of Bennu鈥檚 roughly 500-metre diameter shape 鈥� the most detailed asteroid model to date. OLA and the Canadian science team are funded by the Canadian Space Agency.

Bennu is a near-Earth asteroid that formed in the asteroid belt and found its way into a closer proximity to Earth due to gravitational interactions with giant planets and forces due to heating from the Sun.

The analysis of this shape concludes that Bennu鈥檚 rounder southern hemisphere is caused by a hemispherical difference in the number of large boulders 鈥� a consequence of its formation 鈥� that are holding back finer surface material.聽The research also provides evidence of a past global, spin-related partial disruption that is still expressed in Bennu鈥檚 shape.

Our research on this type of asteroid is important in understanding the evolution the solar system and of the Earth, because it was this type of asteroid that delivered water and organics to the Earth,鈥� says Daly, director of 91亚色鈥檚 Centre for Research in Earth and Space Science (CRESS).

Professor Michael Daly is available for interviews about the findings.

91亚色 champions new ways of thinking that drive teaching and research excellence. Our students receive the education they need to create big ideas that make an impact on the world. Meaningful and sometimes unexpected careers result from cross-disciplinary programming, innovative course design and diverse experiential learning opportunities. 91亚色 students and graduates push limits, achieve goals and find solutions to the world鈥檚 most pressing social challenges, empowered by a strong community that opens minds. 91亚色 U is an internationally recognized research university 鈥� our 11 faculties and 25 research centres have partnerships with 200+ leading universities worldwide. Located in Toronto, 91亚色 is the third largest university in Canada, with a strong community of 53,000 students, 7,000 faculty and administrative staff, and more than 300,000 alumni. 91亚色 U's fully bilingual Glendon Campus is home to Southern Ontario's Centre of Excellence for French Language and Bilingual Postsecondary Education.

TORONTO, Monday, Dec. 11, 2017 鈥� Debris from asteroid 3200 Phaethon, whose namesake is the son of Greek sun god Helios, will put on one of the best meteor showers of the year this week, says of the Faculty of Science.

Dust, grit and bits of rock moving at about 35 km/sec will flare up as they vaporize in Earth鈥檚 atmosphere.

Known as the Geminids meteor shower, dozens of meteors or shooting stars, several likely to be bright and colourful, will streak through the sky creating quite a show, as long as the clouds clear. Although happening most of this month, the height of the meteor display will occur Wednesday night into Thursday morning under near moonless skies.

The best way to see it is to find a dark area as far from lights as possible. However, even city light pollution cannot extinguish this meteor shower for observers. Although the meteors will seem to originate from the Gemini constellation, they can be seen anywhere in the night sky.

Delaney is available to discuss what to expect and why this particular meteor shower is worth braving the winter cold to see.
