2012 LZ 1 is an asteroid classified as near-Earth object and potentially hazardous asteroid of the Amor group, approximately 1 km (0.62 mi) in diameter. [4] It passed within 5.4 million kilometers (14 lunar distances ) of Earth on 14 June 2012. [ 4 ]
2012 TC 4 is a tumbling micro-asteroid classified as a bright near-Earth object of the Apollo group, approximately 10 meters (30 feet) in diameter. [ 6 ] [ 7 ] [ 8 ] It was first observed by Pan-STARRS at Haleakala Observatory on the Hawaiian island of Maui , in the United States.
A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]

An asteroid that’s somewhere between 30 and 100 feet long is hurtling through space in the direction of Earth at 30,000 miles per hour. An asteroid that’s somewhere between 30 and 100 feet ...
The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [8] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
The Virtual Telescope Project will host a free live stream of the comet on its website and YouTube channel starting at 9 p.m. Mountain time/ 8 p.m. Pacific time.
CAMS [3] networks around the world use an array of low-light video surveillance cameras to collect astrometric tracks and brightness profiles of meteors in the night sky. . Triangulation of those tracks results in the meteor's direction and speed, from which the meteors’ orbit in space is calculated and the material's parent body can be identifi
