Rendezvous with Rama

This is the kind of book that reads like a textbook. It is a detailed account of humankind first meeting with an object build by an alien race.

The story takes place in a near future, where other planets have already been colonized and we have probes stationed in space to monitor asteroids, to predict whether they will collide on populated areas.

One of this probes picks up a strange piece of rock in space, that turns out to be made by a long extinct, more technological advanced race.

I stopped reading as the the first chapters all detailed how this perfect spherical rock, that seems to be an artificial made planet, looks on the inside.
