Finally yesterday I started to run again, after several years contemplating the belly was enough to know that Saturn floats on the water more than me to decide. Leaving aside now all the muscles ache and I can not move unless it before I run (that is, to do sports I think it's bad for my physical, because I run my body is less useful if I do not run) I bought a GPS for running routes and not get lost in the mountains if someday I decide to run through the forest to avoid breathing the fumes of cars.
to see where I'm going to run ... I have no idea where to go. I am open to suggestions. Luckily my GPS is one of those modern, brand Tun Tun , which even gives you suggestions of sites to visit (GPS is a button called "Navigate to Tun Tun ). Select this option and asked me how many miles I travel.
Today I feel a whole macho. Let's say I run about 10 km. See what I propose. Look, I said that if I run 10 km, all I have to do is run all the Avenida Diagonal in Barcelona from beginning to end.
I think I bought the GPS of the Junior Woodchucks , because it tells me that 10 km is the distance to the highest clouds in the atmosphere and that the planes are at 10-12 km altitude. How curious! The pileup that I bought is fine. I will explore some more.
How far will the Barcelona to Lleida? I said that about 150 km, the same as the height to which are the Northern Lights in the sky. Ho, ho. This GPS is the peel!
And from Barcelona to Valencia? About 350 km. As the altitude at which the ISS revolves around the Earth. Barcelona How to Pontevedra? The radius of Pluto. "From Barcelona to Warsaw? The radius of the planet Mercury. "From Barcelona to Athens? The radius of the planet Mars. "From Barcelona to Ottawa? The radius of the planet Venus. From Barcelona to Toronto, the radius of the Earth.

I understand now. I just found a GPS option called "Heaven to Tun Tun" which lets you navigate through the universe ... Says that the radius of Neptune and Uranus is like going to the antipodes of the Earth, the radius of Saturn is like a ride and half the world. And the radius of Jupiter, the largest planet in the Solar System, is a world tour and 3 / 4. (About 70000 km in radius). And the sun's radius is about twice the distance from Earth to the Moon. Wow!
Comparison of Solar System planets and the Sun
Meter "Solar System on a football field? How? Anyway, I'll give OK to see what I get ... Go! It shows the distances of the planets from the Sun as if the Sun were in a goal in a soccer field and the (formerly) most distant planet (Pluto) was on the other end.
orbits of the planets of the Solar System on a football field with the Sun and Pluto, the farthest planet in each goal.
Well, I think that the ball must be in the area of \u200b\u200bthe Sun because almost all the planets are in your area. Surely they are launching a corner. Then the team take care of Pluto and not rely because it only have been in court to defend Uranus and Neptune. As has a counter ...
And the stars? What will? No, I do not mean the stars of the football match, which in this case would only be the Sun, but how are the other stars of the Galaxy to the Sun "The Sun is too big or too small?
Man, that the sun was two times the distance to the Moon has hit me, really. So the little sun should not be. In fact, the smallest known star has a size equal to one-eighth the size of the Sun, ie, only slightly larger than Jupiter.
But it is known star with a radius of about 2000 times larger than the Sun, or 700 billion times larger than a person like me 1.80m.
Do you think we killed the size of the stars? In our galaxy there are 100 billion stars. The galaxies are grouped in clusters of galaxies
