April 29, 2020 - An asteroid big enough to destroy Earth, an apocalyptic reminder of the vulnerability of our planet, is due to pass us by on April 29.
Earth-Sky describes the space rock, 1998 OR2, as at least 1.6km (1 mile) wide or possibly 2.5 times that size. According to the publication, it is the largest known of all large Near Earth Objects (NEOs) that will pass us within less than five times the Earth-Moon distance over the next two centuries. It is travelling through space at 31,319km per hour (19,461mph). Asteroid 1998 OR2 is one of the class of NEOs called Potentially Hazardous Objects (PHOs). Its classmates are NEOs whose orbits bring them within 7.5 million km (4.7 million miles) of Earth’s orbit, and that are greater than 140 metres (500 feet) in size.
Space agencies are finding, tracking and characterising NEOs as part of globally-coordinated planetary defence programmes.

Dinosaur-killing asteroid rapidly turned oceans to acid, disrupted climate. When a huge asteroid slammed into the surface of the Earth about 66 million years ago, it left life on the planet in ruins.
The impact caused the last mass extinction event, spelling the end for the dinosaurs. Scientists have long debated exactly how the impact ended the reign of the terrible lizards, with many theories pointing to a disruption of the Earth's climate. New evidence suggests that this is, at least partially, true and that the massive collision caused rapid acidification of the oceans, driving ecological collapse.

Scientists can’t wait. During a 30 April meeting at the 2019 Planetary Defense Conference in College Park, Maryland, researchers reviewed plans to observe the asteroid and discussed possible missions that might be sent to inspect the body at close range. “The Apophis close approach in 2029 will be an incredible opportunity for science,” said Marina Brozović, a radar scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “We’ll observe the asteroid with both optical and radar telescopes. With radar observations, we might be able to see surface details that are only a few meters in size.” Apophis was discovered in June 2004. The Manicouagan impact crater, central Quebec, Canada is 214 million yrs old & was created by a 5km wide asteroid. The crater was originally 100km wide. Its highest point is Mount Babel which is part of the post impact uplift structure. @OpenTopograph. NASA: Threat of Earth-destroying asteroid must be taken seriously.
The head of NASA has warned that it is time to take the threat of an Earth-destroying asteroid seriously.
Jim Bridenstine spoke as the space agency began its planetary defence conference exercises, based around the hypothetical scenario of an asteroid impact. NASA's administrator expressed concern that similar warnings have historically prompted amusement and said that asteroid collisions were more common than people believed. In the planetary defence exercises this week, simulating a global response to an Earth-destroying meteorite, NASA's first step will be to precisely measure the object's speed and trajectory. After that, a decision will have to be made: attempt to prevent the collision by deflecting the asteroid, or evacuate the area it could crash into.
Planetary defence and astronomical experts have warned against humanity destroying large asteroids with nuclear weapons out of the concern that they would simply shatter into smaller dangerous pieces.

US detects huge meteor explosion. Image copyright Getty Images A huge fireball exploded in the Earth's atmosphere in December, according to Nasa.
The blast was the second largest of its kind in 30 years, and the biggest since the fireball over Chelyabinsk in Russia six years ago. But it went largely unnoticed until now because it blew up over the Bering Sea, off Russia's Kamchatka Peninsula. The space rock exploded with 10 times the energy released by the Hiroshima atomic bomb. Lindley Johnson, planetary defence officer at Nasa, told BBC News a fireball this big is only expected about two or three times every 100 years.

If the Barringer Meteor Crater impact event in Arizona occurred in a modern city, it would completely destroy it.
As the question implies, distance from the point of impact is directly related to one’s survival. The key to determining a safe distance lies in the energy of the impact event. Estimates of that energy exist, but the range of uncertainty can have significant consequences. If the energy was sufficiently small, one could have had a spectacular view of the impact event from Anderson Mesa, a long volcanic ridge about 15 miles (24 kilometers) west of the crater. However, for some of the larger energy estimates, that location may have been uncomfortably close, if not deadly. Yes like this. Can you hear meteors? Find out.

Greenland ice sheet hides huge 'impact crater' Image copyright NATURAL HISTORY MUSEUM OF DENMARK What looks to be a large impact crater has been identified beneath the Greenland ice sheet. The 31km-wide depression came to light when scientists examined radar images of the island's bedrock. Investigations suggest the feature was probably dug out by a 1.5km-wide iron asteroid sometime between about 12,000 and three million years ago. But without drilling through nearly 1km of ice to sample the bed directly, scientists can't be more specific. A team of international scientists used @NASA radar data to uncover a meteor impact crater under Greenland’s ice sheet.
