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.
Apophis hitting Earth is possible, study finds, but very unlikely Astronomers have long had their eye on the notorious Apophis, which was initially believed to pose a serious threat to Earth upon ...
It should look somewhat like a bright star streaking across the sky. Earth's gravity will significantly influence Apophis – squeezing and distorting the asteroid as one side is pulled toward our ...
The dwarf planet (523794) 2015 RR 245 will make its closest approach to the Sun of 34 AU. [35] 2094 April 7 Mercury occults Jupiter; it will be very close to the Sun and impossible to view with the naked eye. [31] 2100 March 24 Polaris appears furthest North. Polaris' maximum apparent declination (taking account of nutation and aberration) will ...
Vesta is the brightest of the four main-belt asteroids that can, on occasion, be visible to the naked eye. [70] On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis .
The asteroid was named for the Egyptian god of chaos and darkness and is believed to be shaped like a peanut. One hour after Apophis makes its close approach to Earth on April 13, 2029, OSIRIS ...
Apophis will last be visible from the US east coast about 14 hours before the closest approach (at 7th magnitude, when it is about to cross the Moon's orbit), and an hour or two longer (at 6th magnitude) from the west coast. Naked eye sightings might be possible from dark sites, especially in the south-west of the United States.
The comet will look like a bright fireball with a long, extended tail, said Bill Cooke, lead of NASA's Meteoroid Environment Office at the Marshall Space Flight Center in Alabama, KABC-TV reported.
