There is a very minute chance of an asteroid posing a threat to Earth, especially in recent years. One asteroid is set to make its approach to Earth today but will not pose a threat to the planet.
Known as 2020 SV5, the asteroid is similar in size to the rock that hit Chelyabinsk, Russia back in 2013, measuring at 20 meters in diameter. With its size, even if it should collide with Earth, it will not cause damage on a global scale but on the area it impacts, especially as it enters the atmosphere. It should be noted that the Chelyabinsk incident saw the meteor produce a powerful impact that destroyed thousands of buildings and injuring more than 1,400 people.
SV5 is classified as a Near-Earth Object or NEO and as it passes today, September 30, it will not pose a threat to Earth.
Astronomers reveal that SV5 is hurtling through space and Earthbound at a speed of 13.7 kilometers per second. This is also equivalent to a little less than 50,000 kilometers per hour, making it extremely fast in human terms. When it approaches the planet, SV5 will only get as close as more than three times the distance between the Moon and our own planet.
Aside from asteroids, Earth is about to get caught in another solar storm over the weekend. The solar winds will trigger a geomagnetic storm in the planet’s magnetic field, according to the US Space Weather Prediction Center or the SWPC. The storm will last until today, and SWPC has warned of the solar storm’s possible effects on technology such as power grid fluctuations or impacts on satellite operations.
“Another solar wind disturbance that creates conditions favorable to geomagnetic storms is a high-speed wind solar wind stream,” said the SWPC.
It should be noted that some solar storms can be very weak, but some can also be very strong. A strong solar storm can cause problems for satellite technology, as well as problems for animals that make use of the natural magnetic to navigate. Another effect is that solar storms can produce auroras in the polar regions.
