How long will a golf ball stay in space?
A golf ball to be hit off the International Space Station next week as part of a promotional stunt could stay in orbit for years instead of just days, according to a Russian analysis. But NASA remains confident the ball will burn up in Earth’s atmosphere quickly and will not endanger any spacecraft.
How small can a ball be tracked?
Unfortunately, the ball is too small to be tracked by ground radar. US military radar can track space debris as small as 10 centimetres across, and can sometimes see things as small as 5 cm wide if it is in just the right orbit.
Does the ISS de-orbit quickly?
The difference could be important – NASA scientists prefer that space junk released from the ISS de-orbits quickly, giving it less time to hit the station or other spacecraft, such as the space shuttle, set to launch in December (see Astronauts to pitch unwanted gear off space station ).
Will Tyurin hit a golf ball?
And even though cosmonaut Mikhail Tyurin will not hit the golf ball hard, it will still be flying at thousands of kilometres per hour relative to Earth. So if it hit something, it could cause serious damage, despite its light weight.

What is the largest star in the universe?
Also known as Hershel’s Garnet Star, Mu Cephei is a red supergiant and one of the largest and most luminous stars in our galaxy. Nearing death, Mu Cephei still must be respected. If Earth were the size of a golf ball, Mu Cephie would be as wide as two Golden Gate Bridges stretched end to end. Mu Cephei could hold 2.7 quadrillion Earths!
How far away is Betelgeuse?
But looking a little deeper into space we find a more massive star called Betelgeuse, which is 427 light-years away. Betelgeuse is so big, in fact, that it’s twice the size of Earth’s orbit around the Sun.4 When I first heard that fact as a teenager, it put a serious dent in my prayer life. How do you talk to a God who breathes out stars that huge? ...
