What does "5-point" mean in this context? I could not work it out by looking it up in the dictionary.
Thanks for your help.
This Professor is talking about how the asteroid belt was discovered.
Professor: Yes, I divided all those numbers by 10 by putting in a decimal point. Now I'm gonna write the names of the planets under the numbers. Mercury...Venus...Earth,,, So, what do the numbers mean?
Student: Is it the distance of the planets from the sun?
Professor: Right, in astronomical units-not perfect, but tantalizingly close. The value for Mars is off by...6 or 7 percent or so. It's...but it's within 10 percent of the average distance to Mars from the Sun. But I kind of have to skip the one after Mars for now. Then Jupiter's right there at 5-point something, and then Saturn is about 10 astronomical units from the Sun. Um, well, this pattern is known as Bode's Law.
In this context the professor is being general with their statement. By saying 5 point something, they really mean (5.?) as in, it could be 5.2 or 5.5 but they don't know the exact measurement so they say unspecifically 5 point something.
