A SPEEDING comet will be visible to stargazers today as it makes its closest ever approach to Earth.
The ball of ice, known as the “Incredible Hulk” because of its startling green colour and large size — has entered Earth’s inner solar system for the first time.
Comet C/2017 S3 will pass by our planet just 70 million miles away as it hurtles through space towards the Sun.
Its distinctive glow is caused by cyanide and carbon molecules in the comet reacting to the warmth of the Sun.
First discovered in September 2017, in the past year, the comet has had two surface explosions, one on June 30 this year and a second two weeks later.
“A giant electrified gas cloud”

At first, the comet, which is formally known as PANSTARSS C/2017, could only be seen through a powerful telescope.
But after the explosion at the end of June, it became bright enough to see with binoculars.
Now, experts believe the latest explosions will make it visible to the naked eye.
The gas cloud surrounding the comet is mind-boggling — at 160,000 miles wide it’s around twice the size of the planet Jupiter — and almost 13 times bigger than Earth.
Stargazers will have their best chance of seeing the comet with the naked eye on today, as the cloud of exploding gases around it grows larger.
It will then orbit the Sun, before coming back towards earth at the end of August.
Scientists say a blast of radiation from the Sun may trigger more explosions, making the comet even brighter in the night sky.
Daily Star Online reported recently the Hulk comet could cause electromagnetic disturbances on Earth.
But Russian astronomer Stanislav Short has told local media the Incredible Hulk comet — despite its “threatening approach” toward Earth and tail of “giant electrified gas cloud,” poses no danger to our planet, after its explosions last month.
He added these kinds of space objects pass by our planet regularly.
