<p>We get this information (if not quite as accurately as from dedicated missions like GRACE, whenever we have a probe in orbit around a planet. By tracking it carefully we can get information about the variation in the gravitational field. </p>

<p>I just recently found out about the GRACE Nasa mission which basically mapped out the gravitational anomalies of earth as well as serving extensively in the study of earths geology and the movement of its distribution of water. While I continued reading about it I came across GRAIL which did a similar job but over our moon. </p>

<p>Here for GRAIL: <a href="https://en.wikipedia.org/wiki/Gravity_Recovery_and_Interior_Laboratory" rel="nofollow noreferrer">GRAIL</a></p>

<p>What i'm now wondering is are there space agencies or organizations considering missions to any of the other planets in our solar system and attempting to measure their gravitational anomalies in a similar manner hopefully giving vital information on their inner structure or formation.  </p>

There are no such missions in an advanced state of planning, however we do have a good idea of the gravity field around Mars, gleaned from observations of anomalies in the orbits of the various orbital probes.

These data were gathered into a [map of the gravity field of Mars](https://www.nasa.gov/feature/goddard/2016/mars-gravity-map)

According to that NASA article:

> The map was derived using Doppler and range tracking data collected by [NASA's Deep Space Network](http://deepspace.jpl.nasa.gov/) from three NASA spacecraft in orbit around Mars: [Mars Global Surveyor](http://marsprogram.jpl.nasa.gov/mgs/) (MGS), [Mars Odyssey](http://mars.nasa.gov/odyssey/) (ODY), and the [Mars Reconnaissance Orbiter](https://www.nasa.gov/mission_pages/MRO/main/index.html) (MRO).

Also the [Juno Spacecraft](https://en.wikipedia.org/wiki/Juno_(spacecraft)) has made detailed measurements of Jupiter's internal structure via maps of it's gravity field as well.
