    {
        if(Greenfoot.isKeyDown("w") )
        move(5);
        if(Greenfoot.isKeyDown("s") )
        move(-5);
        if(Greenfoot.isKeyDown("d") )
        turn(5);
        if(Greenfoot.isKeyDown("a") )
        turn(-5);
        if( is.Touching (Asteroid.class) )
        Greenfoot.stop();
    }
}

The compiler does not know what object "is" refers to. Nor does it know of any "Touching" method (even if "is" referred to an Actor object). But, it does know about an "isTouching" method for an Actor object. Remove the "." from line 13.
