- This nearly polar orbit is designed such that the spacecraft's orbital path moves at the same apparent rate as the Sun.
- This creates increased atmospheric drag on spacecraft in low orbits, shortening their orbital lifetime.

- In addition, it can also lead to daunting calculations as each atom contributes its orbitals to the whole molecule.
- The effect is due to the distortion of the electron orbitals because of the magnetic field.
- It is also possible for two orbitals on each atom to overlap, forming two molecular orbitals between the two atoms.
