Pequeño tamaño (2 metros de diámetro)
(+2)
This small car-sized asteroid was discovered *after* its flyby at just 428 kilometers from Earth. Its late detection highlights the challenges in identifying small objects.
Órbita inusual totalmente dentro de la órbita de Venus
(+3)
This 700-meter-diameter asteroid remained hidden under the Sun's glare and follows an unusually close orbit to Earth. Its discovery highlights the importance of new techniques for detecting 'twilight' asteroids.
Roca de unos 20-25 metros de diámetro
This rock, about 20-25 meters in diameter, was detected a few weeks before its passage at 1.2 million kilometers from Earth. It is an example of continuous monitoring of near-Earth objects.
No supuso ningún riesgo
(+1)
This asteroid, though small, is notable for its high speed, traveling at over 20 km/s. Its tracking is important for understanding the behavior of fast and small objects.
Pasa cerca de la Tierra
(+2)
This slightly larger asteroid shows changes in brightness every few hours due to its rotation. Its observation contributes to the understanding of the physical and rotational characteristics of asteroids.
