A MONSTER asteroid * the size of New South Wales pbades over the Earth so close that it can be seen without a telescope.
But do not worry. It will not hurt us.
NASA has accurately calculated the orbit of the space rock *
Even if it is visible, it is 170 million kilometers away. And the track that follows is never likely to cross that of our own planet.
But we can see the glowing, yellow sphere that crosses our sky because of its size and composition. It is more reflective than our moon, which means that light bounces on what we can see.
It will be visible until it goes into view on July 17th. Search Him in the sky near Mars, Saturn and the constellation Sagittarius.
Named 4 Vesta, it's the second most mbadive object in the asteroid belt * between Mars and Jupiter
It moves at 19.3 km every second and takes 3.6 years to complete each of its orbits
The space debris beam * is 845 km wide, giving it a total area of about 800,000 square kilometers. New South Wales has an area of 809,444 km2
This seems huge. But that seems even greater if we consider that the asteroid that caused the end of the dinosaur era was only 15km wide
What makes it different from other asteroids, it's its density *. Its material is more compact, or closely packed, than most others. But it is not mbadive enough to make it a real dwarf planet, like the neighboring dwarf planet of Ceres.
Vesta was discovered in 1807 and was named after the Roman goddess of the house. It was orbited by the Dawn space probe in 2011. Scientists believe that it includes basalt areas – a type of rock that we have on Earth – which means that it has poured lava on its surface.
pole, cutting deeply into his interior. There is also a mbadive mountain that dominates the rest of the surface of the asteroid about 20km, the second highest mountain of the solar system known
