99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
Graphical representation of the Torino scale. The sizes are approximate. Energy is in TNT equivalent.. The Torino scale is a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets.
The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3% as more observations are made. ... Among those objects is Apophis, the cruise ship-sized ...
A space rock the size of a cruise liner will closely pass Earth in April 2029. While the asteroid Apophis won’t hit Earth, two spacecraft may tag along.
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
The Palermo scale was devised for astronomers to compare impact hazards at a technical level, rather than for the general public. [2] It was adopted at the meeting of the Working Group on Near-Earth Objects of the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space which was held in Palermo, Italy, on June 11–16, 2001.
In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a ...
The asteroid with the greatest chance of impacting Earth in 2025 is 2009 VA (6-meters in diameter) with less than a 1-day observation arc. [8] It has a 1:48,000 chance of impact on 06 November 2023, but is expected to be around 0.3 AU (45 million km ) from Earth on that date with uncertainty region of ± 900 million km. [ 10 ]
