The Jet Propulsion Laboratory (JPL), which monitors celestial objects, has discovered an asteroid approaching Earth that is approximately 1.3 kilometers in diameter. The object, labeled as potentially hazardous, will make a near encounter to Earth on March 4, getting as close as 49,11,298 kilometers. 136971 (2001 CB21), a near-Earth object, circles the Sun. In only 400 days, it will complete its orbit. The speed of the closest space object to Earth is 43,238 kilometers per hour. In 2006, NASA stated that the asteroid passed within 61,71,250 kilometers of Earth.
On March 4, the asteroid will pass Earth at a distance of only 46,15,555 kilometers. In March 2043, it will complete its next orbit. NASA’s Virtual Telescope Project has released photographs of the asteroid. When JPL detected orbit, Gianluca Aunty, an astronomer from the Italian Virtual Telescope Project, could photograph this floating object in space. Auntie captured an asteroid 35 million kilometers from Earth using an Earth-based telescope.
While the orbit was given by JPL, astronomer Gianluca Masi of the Virtual Telescope Project in Italy captured the object floating in space, speeding towards us. Masi captured the asteroid using a land-based telescope about 35 million kilometers distant from Earth.
The 138971 (2001 CB21) was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) program, which has been responsible for nearly 24% of all known potentially dangerous asteroids discoveries. The program has observed more than 14 million asteroids and comets, which has detected 6,001 new objects, including 142 previously undiscovered NEOs, four potentially dangerous objects, and eight new comets.
Last year, NASA achieved a significant milestone by discovering the 1000th near-Earth asteroid (NEA). NASA radars have detected PJ1 in the year 2021. This study, which began in 1968, is progressing with tremendous precision. The radar identifies fast-moving objects and aids in understanding NEO orbit by astronomers. It’s also assisting in accurately predicting whether or not the asteroid will strike Earth.
