Four Very Young Asteroid Families Discovered By Scientists

Publicado em 01 outubro 2018

Four new families of very young asteroids have been identified by Brazilian scientists, taking the sum to 13. The 4 families—that are less than 7-million-years old—revolve between Mars and Jupiter as an element of a consortium called the Main Asteroid Belt. The scientists dated these families making use of a numerical simulation technique to process existing information to revisit the time of the asteroid formation period.
A Sao Paulo State University Professor, said, Valerio Carruba, “We recognized the new families using numerical simulation utilizing the BIM (backward integration method), which is much more accurate than other techniques utilized for dating asteroid families. However, BIM only functions for actually young families which are less than 20-million-years old. Founded on existing information, BIM enables one to revisit the time utilizing numerical simulation to rebuild the situation wherein the parameters were allied and thus date the asteroid family.”
The Main Belt is an amazing slot of asteroids, with over 700 known entities. The digit is increasing progressively thanks to enhancing techniques of identification and it can be projected at a million. The asteroids within the Main Belt are distant from evenly distributed ones, as per Carruba. Several diverse areas have shaped within the belt on account of the extremely complex gravitational interface among so many bodies and, in particular, to the strong gravitational field of Jupiter.
On the other end, Hayabusa 2 mission of Japan, subsequent to months of flying around its target, has touched down on the asteroid’s surface. Two of the landers of the host spacecraft (ROVER-1B and 1A) have got down on the plane of the asteroid 162173 Ryugu and already have been jumping around as they capture images and measure the temperature of the space rock. Also, Hayabusa 2 is poised to set-off ROVER-2 that adds ultraviolet and optical LEDs to locate floating dust particles.
