Although there is a very small chance of an asteroid collision, the chances are still there, which is why space agencies are now taking steps in developing measures that could protect the planet from major collisions.
What if an asteroid hit the Earth? "Landing on Titan, mapping the Universe with Herschel and Planck, hunting a comet with Rosetta and now preventing Earth against Asteroid, all so awesome and unimaginable challenges our company is so proud to face".
Hera, set to be about the size of a desk, should navigate autonomously around the asteroid while it collects data.
Onto more asteroids, this week saw one particular rock fly closer to Earth, known as 2020 RF3.
Two asteroids have shot past the Earth this week, coming closer to the planet than the Moon - and more close encounters are expected during the rest of the year.
Still with 11 million kilometers between us and the system, the cumulative change in the trajectory would surely remove the collision with our planet - and that certainty would be assured by Hera, which will follow the system for the remaining years until it arrives in our neighborhood.
NASA's OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is scheduled to swoop down to asteroid Bennu on October 20 and bring the sample back to Earth in September 2023.
Asteroidn2014 QJ33 is a classified Near-Earth Object (NEO) hailing from the group of Apollo asteroids, according to NASA. The effect of such an impact would be devastating if it reached a populated area, capable to destroy an entire city or to create a tsunami if it impacted a sea. The system comprises about 15 percent of all known asteroids.
Dimorphos has a diameter of nearly 525 feet - which is about the width of the Great Pyramid of Giza in Egypt.
It passed 94,000 kilometers (58,500 mi) after September 14. Dimorphos will thus become the first object in the Solar System whose orbit and physical characteristics have been measurably modified by human effort. Therefore, the worldwide community joined forces through the Asteroid Impact & Deflection Assessment ("Assessment of the impact and deflection of the asteroid" - AIDA) in the search for an effective plan in case an object threatens the Earth.
It should catch up with Dimorphos in late 2026 for a six-month survey. Thales Alenia Space sees space as a new horizon, helping to build a better, more sustainable life on Earth.
