The individual uses the handle @_time_traveller_2269 on Tiktok. The TikToker claimed that the asteroid's radius might be as large as 868.7 kilometers. Sharing the warning in a 10-second video, the user said (per Daily Star): "This is no joke!! I am a time traveler from the year 2269. Social media users were divided on the claim. Some individuals stated that the warning should be taken seriously, while others felt that the claim was incorrect. The rest of the netizens, on the other hand, appeared unconcerned with the news. One user complimented the time traveler and warned others not to do the same." However, the alleged time traveler was primarily mocked for issuing the warning. One jokingly commented, "I'm a time traveler from 1963; sorry I'm late." Another asked: "And I'm Mickey Mouse? Did u get the lottery numbers by any chance?" @tiktok|https://www.tiktok.com/@_time_traveler_2269_/video/7097305362541415685?_t=8SKIucp0hC2&_r=1@ ALSO READ: Asteroid Flyby This May: Space Rock Larger Than Empire State Building Will Pass Near Earth on Sunday Other Space Rocks To Pass By Earth This MonthThe announcement comes after astronomers warn that a massive asteroid is on its way to Earth. The giant space rock Asteroid 388945 (2008 TZ3) will approach Earth on May 16, according to the National Aeronautics and Space Administration (NASA), which is monitoring it. According to NDTV, the asteroid is also 1,608 feet wide. The Empire State Building in New York is 1,454 feet tall. It's also bigger than the Statue of Liberty and the Eiffel Tower combined. If the space rock collides with the Earth, it may cause widespread devastation. The space rock is considered "potentially hazardous" by experts, Republic World reported. According to estimates from space specialists, it will pass us by at a distance of 2.5 million miles on May 27.
Although "potentially hazardous," experts assured that the people have nothing to worry about because it will pass by at a safe distance of around 4 million kilometers, more than 10 times the distance between the Earth and the moon. Surprisingly, the space rock was photographed by the Virtual Telescope days before it made its closest approach to Earth. According to astronomer Gianluca Masi, this asteroid is 1.8 kilometers large and was observed at a distance of 18.7 million kilometers from Earth. As its name implies, the asteroid was discovered in 1989 by astronomer Eleanor Helin of the Palomar Observatory in California.

But this event wasn’t a complete surprise: Astronomers knew it was on a collision course, predicting exactly where and when the impact would happen. Two hours before the asteroid made impact, K. Sarneczky at the Piszkéstető Observatory in northern Hungary first reported observations of the small object to the Minor Planet Center – the internationally recognized clearinghouse for the position measurements of small celestial bodies. The object was posted on the Minor Planet Center’s Near-Earth Object Confirmation Page to flag it for additional observations that would confirm it as a previously unknown asteroid. NASA’s “Scout” impact hazard assessment system then took these early measurements to calculate the trajectory of 2022 EB5. As soon as Scout determined that 2022 EB5 was going to hit Earth’s atmosphere, the system alerted the Center for Near Earth Object Studies (CNEOS) and NASA’s Planetary Defense Coordination Office, and flagged the object on the Scout webpage to notify the near-Earth object observing community. Maintained by CNEOS at NASA’s Jet Propulsion Laboratory in Southern California, Scout automatically searches the Minor Planet Center’s database for possible new short-term impactors. CNEOS calculates every known near-Earth asteroid orbit to improve impact hazard assessments in support of the Planetary Defense Coordination Office. “Scout had only 14 observations over 40 minutes from one observatory to work with when it first identified the object as an impactor. We were able to determine the possible impact locations, which initially extended from western Greenland to off the coast of Norway,” said Davide Farnocchia, a navigation engineer at JPL who developed Scout. “As more observatories tracked the asteroid, our calculations of its trajectory and impact location became more precise.” Scout determined that 2022 EB5 would enter the atmosphere southwest of Jan Mayen, a Norwegian island nearly 300 miles (470 kilometers) off the east coast of Greenland and northeast of Iceland. At 5:23 p.m. EST (2:23 p.m. PST), 2022 EB5 hit the atmosphere as predicted by Scout, and infrasound detectors have confirmed the impact occurred at the predicted time. From observations of the asteroid as it approached Earth and the energy measured by infrasound detectors at time of impact, 2022 EB5 is estimated to have been about 6 1/2 feet (2 meters) in size. Tiny asteroids of this size get bright enough to be detected only in the last few hours before their impact (or before they make a very close approach to Earth). They are much smaller than the objects that the Planetary Defense Coordination Office is tasked by NASA with detecting and warning about. “Tiny asteroids like 2022 EB5 are numerous, and they impact into the atmosphere quite frequently – roughly every 10 months or so,” said Paul Chodas, the director of CNEOS at JPL. “But very few of these asteroids have actually been detected in space and observed extensively prior to impact, basically because they are very faint until the last few hours, and a survey telescope has to observe just the right spot of sky at the right time for one to be detected.” A larger asteroid with hazardous impact potential would be discovered much farther from Earth. NASA’s goal is to keep track of such asteroids and to calculate their trajectories in order to have many years’ notice ahead of a potential impact should one ever be identified. But this real-world event with a very small asteroid allowed the planetary defense community to exercise capabilities and gave some confidence that the impact prediction models at CNEOS are highly capable of informing the response to the potential impact of a larger object. 2022 EB5 is only the fifth small asteroid to be detected in space before hitting Earth’s atmosphere. The first asteroid to be discovered and tracked well before hitting Earth was 2008 TC3, which entered the atmosphere over Sudan and broke up in October 2008. That 13-foot-wide (4-meter-wide) asteroid scattered hundreds of small meteorites over the Nubian Desert. As surveys become more sophisticated and sensitive, more of these harmless objects will be detected before entering the atmosphere.

How big is the asteroid that's coming in 2022?Asteroid 2002 RM4 has been estimated by astronomers to be between 360-809 yards/330-740 meters wide. So at it's very largest it could be as wide as the world's tallest building is tall. Astronomers at the Pan-STARRS 2 telescope in Haleakala, Hawaii on September 12, 2022, discovered 2022 RM4.
How big will the next asteroid hit Earth?99942 Apophis is a near-Earth asteroid and potentially hazardous asteroid with a diameter of 370 metres (1,210 feet) that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
How big is the 2027 asteroid?An asteroid, named "2019 PDC", was discovered that will come dangerously close to the earth 8 years from now, on April 29, 2027. The space rock is between 330 and 1000 feet in size, somewhere in between the length of 6.5 school buses to the height of two Washington Monuments stacked on top of each other.
Is there an asteroid about to hit Earth?“There are no known [sizable] asteroids on a collision course with Earth for the foreseeable future. NASA always makes information about NEOs available at cneos.jpl.nasa.gov/sentry,” said Nancy Chabot, a planetary scientist at Johns Hopkins Applied Physics Laboratory.
