The asteroid's apparent magnitude at that time will be about 11.5, rendering it unobservable to the unaided eye. At the time of closest approach, 2014 RC will be approximately one-tenth the distance from the center of Earth to the moon, or about 25,000 miles (40,000 kilometers). Moreover, it’s also important to point out that 2020 NO is set to pass by the moon at a distance of a mere 296,592 which is considered a close shave in astronomical terms. “In highly alarming news from NASA’s Center for Near Earth Object Studies (CNEOS), asteroid hunters have identified a ‘potentially hazardous’ asteroid due to pass Earth in September at a paltry distance of 71,805km – just one-fifth of the distance between us and the Moon (384,399km). Earth had a close encounter this morning when Asteroid 2019 OK sped by at 1:22 GMT, at a speed of nearly 55,000 miles (88,500 kilometers) per hour. 3 Juno: 245: 2,67: 0,218 : 13° 324 Bamberga: 240: 2,68 ... Ceci s’explique très bien car le diamètre intervient moins, dans l’éclat de l’objet, que la distance au Soleil et à la Terre (laquelle vue de Chiron, ne s’éloigne jamais beaucoup du Soleil). Juno is the third asteroid to be discovered, and it happened in 1804. It is located in the asteroid belt, and it is the 11 th-largest asteroid, and one of the two largest stony S-type asteroids. The Earth flyby gravity assist was planned as part of Juno’s trajectory to increase the spacecraft’s speed relative to the Sun so that it is sufficient to reach Jupiter.

The closest it came to Earth … The US space agency has apparently labeled 2020ND as a Potentially Hazardous Asteroid (PHA), as "all asteroids with an Earth minimum orbit intersection distance (MOID) of 0.05 … Designated as 3 Juno, this asteroid contains around 1% of the total mass of the asteroid belt.

Les éléments orbitaux, assez variables, sont données avec une précision modérée. Keep your eyes the sky as September may be an eventful month. However, amateur astronomers with small telescopes might glimpse the fast-moving appearance of this near-Earth asteroid. The asteroid, 2020ND, whose 170-meter diameter would dwarf landmarks such as the London Eye, is expected to approach Earth at a distance of around 0.037 astronomical units (around 5.5 million kilometers). One AU (149,598,000 km) is the distance between the Earth and the Sun, so come Saturday, the asteroid will be 5,086,327 kilometres from our planet - a hair's width in astronomical terms.
Key Facts & Summary. Asteroid 2020 NO appears to be the real culprit which JPL data claims will graze Earth from a distance of just 481,459 miles.
