As an Apollo-class asteroid, Nereus’ orbit steadily places it near Earth. Its orbital resonance is roughly 2:1, that means that it orbits almost twice for every orbit of the Earth. This makes a mission to discover the asteroid very possible.
Nereus will come the closest to our planet it has been up to now 20 years, but it set to go 7.4 million km away, which is about 10 instances the space between the Moon and Earth.
No missions are presently identified to be able to discover Nereus, nonetheless it has been thought of earlier than. Each NASA’s Close to-Earth Asteroid Rendezvous-Shoemaker (NEAR) robotic mission and the Japanese Hayabusa mission appeared into Nereus as goal, however each ultimately selected different choices.
In line with NASA, if a mission were to be launched this yr, it could take anyplace between 426-146 days, although the delta-v this time round can be round 10.37 km/s, barely greater than launching a rocket into low-orbit.
Asteroid exploration is a significant area in astronomy, with house businesses, governments and private companies already concerned in learning them as supply of water and minerals.
Luxembourg, one of the first countries to set its eyes on the opportunity of mining celestial our bodies, created in 2018 a Space Agency (LSA) to spice up exploration and business utilization of sources from Close to Earth Objects.
Not like NASA, LSA doesn’t perform analysis or launches. Its objective is to speed up collaborations between financial challenge leaders of the house sector, traders and different companions.
Practically 9,000 asteroids bigger than 36 meters (150 ft) in diameter orbit close to Earth. Geologists consider they’re filled with iron ore, nickel and treasured metals at a lot greater concentrations than these discovered on Earth, making up a market valued in the trillions of dollars.
Different house ventures within the works embody plans to begin mining the Moon as early as 2025, monitor house particles, construct the first human settlement on Mars, and billionaire Elon Musk’s personal plan for an unmanned mission to the purple planet.
