Animation showing Earth's orbit. Then the type of planet the Roman Space Telescope will be able to directly observe: roughly Neptune size in a 1.6AU or greater orbit. And, finally, the type of planet at the current limit of direct observation: Jupiter-size or larger and 40AU from its host star.

Animation showing the locations of the Earth-sun Lagrange points, places where gravitational effects create stable locations that a satellite can remain it with minimal effort. The Roman Space Telescope will orbit at L2, about a million miles away from Earth.

Animation showing the difference between the type of planet the Roman Space Telescope will be able to directly image, versus the type of planet most commonly discovered through other methods.
