In season two of The Expanse, (episode 5, "Home") when
Eros starts moving towards Earth and becomes invisible to missiles
a suggestion is made to tag the asteroid with a laser beam from Rocinante.
The way I understand it, Rocinante is moving from the Belt; missiles are launched from Earth. They're on opposite sides of Eros.
Since this guidance relied on missiles following the laser beam, how was it supposed to work since the beam was on the opposite side of the asteroid?
