Nasa warning as TWO asteroids to zoom past Earth today – following a pair of near misses early this morning

TWO asteroids are going to shoot past Earth this afternoon.
They follow another two space rocks that made close approaches this morning.
All of the asteroids are on Nasa's close approach list.
Asteroid 2020 RB6 should skim past our planet around lunchtime.
Nasa estimates that it's anywhere between 72 to 157 foot.
That means it could be twice the height of Buckingham Palace.
Asteroid 2020 RB6 should come within around 1.6 million miles of Earth.
It's thought to be travelling at a speed of around 44,000 miles per hour.
In the grand scheme of space this isn't a large distance at all, so Nasa has still flagged it as a "close approach".
Any fast moving space object that comes within around 4.65 million miles is considered to be "potentially hazardous" by cautious space organisations.
This means Asteroid 2020 RU7 also makes the close approach list.
The second near Earth asteroid of the day should pass us at around 15:46 UTC.
Nasa thinks it measures up to 167 foot and could come within 3.7 million miles of our planet.
The space agency thinks it will shoot past at a speed of 14,000 miles per hour.
What's the difference between an asteroid, meteor and comet? Here's what you need to know, according to Nasa... Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth) Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids Meteor: If a meteoroid enters the Earth's atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it'll look like a streak of light in the sky, because the rock is burning up Meteorite: If a meteoroid doesn't vapourise completely and survives the trip through Earth's atmosphere, it can land on the Earth. At that point, it becomes a meteorite Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vapourising)
In other space news, plans for a new reality show that will send one winner to space for 10 days have been revealed.
A huge new storm has been spotted on Jupiter .
And, acids may have destroyed any evidence of ancient life on Mars , according to a new study.
