3d object rotation

Hi!

I Just make 2 sphere which one of them is orientated on origin and the other positioned on far from origin.

then I want to rotate just origin sphere in z axis so it may looks like not changed I think.

but it rotating like double star.

please help me.

erad = 6000;
prad = 6000;
npanels = 180;
hold on;

axis equal;
axis vis3d;

[x, y, z] = ellipsoid(0,0,0,erad,erad,prad,npanels);
globe1 = surf(gca,x,y,-z,'FaceColor','none','EdgeColor',0.5*[1 1 1]);
globe2 = surf(gca,x+30000,y,-z,'FaceColor','none','EdgeColor',0.5*[1 1 1]);
view(3);

for i=0:100
    rotate(globe1,[0 1 1],20); % I want just rotate globe1 
    pause(0.2);
end

Keep you axes limits consistent. That should help when viewing.

figure
erad = 6000;
prad = 6000;
npanels = 180;
hold on;
axis equal;
axis vis3d;
[x, y, z] = ellipsoid(0,0,0,erad,erad,prad,npanels);
globe1 = surf(gca,x,y,-z,'FaceColor','none','EdgeColor',0.5*[1 1 1]);
globe2 = surf(gca,x+30000,y,-z,'FaceColor','none','EdgeColor',0.5*[1 1 1]);
view(3);

xlim([0 40000])
ylim([-20000 20000])
zlim([-10000 10000])

for i=0:100
    rotate(globe1,[0 1 1],20); % I want just rotate globe1 
    pause(0.2);
end

@Kevin Holly I want Globe 1 to rotate on its own and Globe 2 to stand still. The code above looks like globe1 orbits globe2.

I solve this problem just change like this

rotate(globe1,[0 1 1],20); --> rotate(globe1,[0 1 1],20,[0 0 0]);
