Question: User: Create a realistic 3D science animation explaining why satellites stay in orbit. Show a detailed satellite with solar panels travelling around Earth. Demonstrate how gravity continuously pulls it inward while its sideways motion carries it around Earth’s curvature. Show a gravity arrow pointing toward Earth’s centre and a velocity arrow tangent to the orbit. Then demonstrate an elliptical orbit, with the satellite moving faster near Earth and slower farther away. Use realistic sunlight, a thin atmospheric glow, and smooth camera movement. Keep labels minimal and clearly separated from objects.
