The house-sized asteroid, which could cause damage to a city if it struck the planet, will hurtle past us at over 16,000 miles per hour.
It is the second previously unknown asteroid recently detected to pass between the earth and moon in the past three weeks, prompting fears that we may soon face an unexpected direct hit from an unseen space rock.
The close shave can be watched live on the Slooh Telescope internet channel.
A Slooh spokesman said: "An asteroid the size of a house will pass between the Earth and the Moon just days after its discovery, causing consternation across the globe.
The asteroid was only just discovered and will pass tomorrow.
"Asteroid 2017 BX, nicknamed Rerun in honor of the beloved, late actor Fred Berry, will make its close approach just before 5am (GMT) on Wednesday morning."
You can watch live Slooh footage of the asteroid as it approaches by clicking back on this story from 10.30pm tonight.
During the broadcast, Slooh Astronomers will be on hand to answer questions about the newly discovered asteroid.
The spokesman added: "They’ll discuss its size, speed and makeup, while also exploring why smaller asteroids like Rerun and its larger cousin so often go undetected until just days before they reach their closest point to the planet."
Rerun, or NEA 2017 BX, was first discovered on January 20.

An asteroid the size of a house will pass between the Earth and the Moon just days after its discovery, causing consternation across the globe.
It is between 13-46 feet in diameter, is moving at a relative velocity of 16,600 miles per hour, and will make its closest approach to the Earth at 4.54am (GMT) on Wednesday, January 25.
At the time of its closest approach, Rerun will be only 162,252 miles away from earth, 30 percent closer than the Moon.
NASA admits it is scouring near space for all potentially hazardous asteroids, but has so far only found 10 to 15 percent of those out there.
It is also working to develop ways to deflect an asteroid on course for an impact.
But, the US space agency claims it knows of none that is likely to hit us for several hundred years.
