Just a Lonely Sphere

I’m just a lonely sphere
Warming your atmosphere    
I am your son, but have no mother

There are millions out there like me 
Strewn about this galaxy
I am your son, I have no brother

And I’m hotter than ten topless babes
One million Centigrade
I am your son, I have no lover

Middle-aged mid-sequence
Seeks companion (and more maybe)
Lover of physics and astronomy,
Serious calls only, please

Now I’m just a lonely sphere
And I’ll cry ten billion tears 
I am your son through rain and weather
I am your sun, you got no other
