Earth Got Closer to The Milky Way’s Supermassive Black Hole – Are We in Danger?

Earth Got Closer to The Milky Way’s Supermassive Black Hole – Are We in Danger?

Earth flies along with the entire Solar System in a straight line through space, and there’s no such thing as a pitstop in this mysterious cosmic journey. The supermassive black hole known as Sagittarius A is located at the center of the Milky Way galaxy, and it acts in an unexpected way. Our galaxy wouldn’t probably exist anymore without that black hole.

Thanks to a Japanese radio astronomy project known as VERA and data gathered by it using a technique called interferometry, scientists discovered that our planet is 2,000 light-years closer to Sagittarius A* than astronomers initially thought.

No reason to worry

Earth is definitely not on a collision course with the supermassive black hole Sagittarius A. If our planet will ever fall into the black hole in the very far future, chances are 99.99 percent that humanity is long gone for millions of years.

VERA operators managed to pinpoint the location and velocity of about 99 specific points in our galaxy. Therefore, the conclusion was that the supermassive black hole Sagittarius A from the center of our galaxy is located 25,800 light-years from Earth, meaning 2,000 light-years closer than scientists initially thought.

More accurate model of the Milky Way

The discovery not only rules out any apocalyptic scenario for our planet in the near future, but it grants a more accurate model of our Milky Way galaxy. But the good news is far from over, as VERA’s new observations reveal a new measurement for the speed of the Earth around the center of the galaxy. 227 kilometers (141 miles) per second is the newly discovered speed, which is significantly faster than previous models that were standing for 220 kilometers (136 miles) per second.

The approximate distance between Earth and the Sagittarius A black hole is 25,640 light-years, with the latter object being located near the border of the constellations Scorpius and Sagittarius.
