It will be followed by 2018 UQ1 two days later – a 470ft (142m)-wide space rock that'll be 2.5 million miles (4.1 million km) away – and 2016 WH a week on Sunday.Ī city-destroying asteroid about the size of the Leaning Tower of Pisa could hit Earth on Valentine's Day in 2046. This 212ft (65m)-wide asteroid, named 2023 DM, will be around 1.9 million miles (3.2 million km). The nearest of the next five space rocks to come close to Earth will be 2023 DM next Wednesday. It measures a colossal 620ft (190m) wide and will come much closer to our planet than its fellow visitor a day earlier.Ģ023 CM will be just under 2.5 million miles (4 million km) away - 10 times the distance of the moon from Earth. This is much bigger than both 2020 FV DW. Twenty four hours after 2020 FV4's approach on March 13, another asteroid known as 2023 CM will hurtle past us. Looking at the here and now, stargazers who want to keep an eye on space rocks that are soaring past Earth over the next weeks and months can keep checking back into NASA's 'Eyes on Asteroids' map. Scary though this may be, that is a generation away. The predicted impact zones of 2023 DW stretch from the Indian Ocean to the Pacific Ocean and the west to the east coast of the US - with Los Angeles, Hawaii and Washington DC all possibilities. This 160ft asteroid caused a nuclear explosion that would have destroyed a large metropolitan area - but it landed in a forest, flattening more than 80 million trees. If it did, the impact would be comparable to the Tunguska 12-megaton event that slammed into Siberia 114 years ago. What might, however, is the 165ft (50m)-wide 2023 DW, which NASA has revealed has a one in 560 chance of impacting Earth on Valentine's Day in 2046.
