Holger Krag, head of the European Space Agency's Space Debris Office, said that, on average, 100-200 tons of space junk enters the Earth's atmosphere every year.
This number also includes spacecraft that have reached the end of their lifetimes and are brought down to Earth in a controlled manner. Most of these end up in an uninhabited part of the Pacific Ocean, minimizing risk to human life. However, others like the Persei booster do not get the chance for that.
At about 33 feet , the Persei booster weighed about four tons while carrying about 16 tons of propellant onboard. And most of the propellant would have burnt upon re-entering the Earth's atmosphere, Jonathan McDowell, an astronomer at the Center for Astrophysics - Harvard & Smithsonian told CNN while tweeting that the object does not pose a threat to us.
To be clear, I do NOT regard this object as a significant risk. Reentries for a object with dry mass of about 4 tonnes may see some debris reach the ground, but not much.
