“Close encounter and impacts with Terrestrial planets: Dynamical studies and observations”
ABSTRACT
The inner solar system contains very interesting planets in the so-called habitable zone. They are Venus, Earth and Mars. During their existence, they suffered many collisions with smaller bodies—The Earth, in particular, where a huge collision is supposed to have created the Earth–Moon system more than 4 billion years ago. The most violent era was the Late Heavy Bombardment (LHB) which ended about 3.8 billion years ago, but collisions of planetary scale continue to the present day.
My interest is the study of orbits and the origins of the minor bodies which have collisions and close encounters with the terrestrial planets after the LHB. I will present some of my dynamical studies on the orbital evolutions of minor bodies of the solar system and their interactions with the terrestrial planets, plus some observations and photometric studies I have done of comets and asteroids.
Refreshments will be available.
