Unexpected tokens in a header

Hi everyone! I'm coding a solar system simulator, and it worked quite good till this morning. I must have done something wrong, but I really can't get what. Maybe a fresh look (or an expert eye ;) ) can see my fault.

I get the error (for every file that includes "solsys.h")

Code:

---

d:\cpp\solsys\src\solsys.h(29) : error C2629: unexpected 'class SolarSystem::Orbit ('
d:\cpp\solsys\src\solsys.h(29) : error C2334: unexpected token(s) preceding ':'; skipping apparent function body

The content of solsys.h is here:

I tried to comment everything above the Orbit class definition, leaving only the header guard and the namespace declaration, but to no good. If it helps, here is the contents of "vectors .h" too, but the error shouldn't be caused by that (it was issued even when "#include "vectors.h" was commented):

Code:

---

#ifndef __VECTORS_H__
#define __VECTORS_H__ 1

#include <vector>
using std::vector;
#include <ostream>
using std::ostream;

namespace math
{

enum Coordinate
{
        X,
        Y,
        Z,
        K
};

class Vector
{
public:

        Vector(int size);
        Vector(double x, double y, double z);

        double &operator[](const int dim)
        {
                return this->data.at(dim);
        }

        double operator*(Vector &b);
        Vector &operator*=(double b);
        Vector operator*(double b);
        Vector &operator+=(Vector &b);
        const Vector operator+(Vector &b);

        double length(void);

        friend ostream &operator<<(ostream &os, Vector &v);

Thanks to everyone!

You are missing one colon after the meanAnomaly parameter in your ctor´s parameter list.

Beaten to it... :)

So I could look above the ctor till the end of time! Thanks to both of you!
