|

<p className="text-l text-white">In 1957, 2019 CD2 asteroid passed 46,349 mi from Earth, with a diameter of 850-1940 ft. This is relatively large, and with this asteroid's orbit around the sun it will have at least 5 more close approaches in the future (although not as close).</p>
|
||||
<p className="text-l text-white">In 2029, 99942 Apophis, an asteroid of around 1,115 ft in diameter, will pass 23,619 mi from the Earth.</p>
|
||||
<p className="text-l text-white mb-10">The near-earth object everyone recognizes is Halley's Comet. With observations going back 2,000 years, the comet approaches the earth every 76 years. The comet is large, being about 48,000 ft by 26,000 ft. Thankfully the closest approach has been 0.033 AU (3 million miles), in 837 AD.</p>
