Julia-based toolkit for dynamical simulations of planets and small solar system bodies.

## Installation

```julia

using Pkg

Pkg.add(url="https://github.com/Astroshaper/AsteroidGravityFields.jl")

using AsteroidGravityFields

```

You can update the module and run tests as follows.

```julia

Pkg.update("AsteroidGravityFields")

Pkg.test("AsteroidGravityFields")

```

## Gravity calculation for asteroids

You can calculate the precise gravity field of an irregularly shaped body, based on the constant-density polyhedron method (Werner & Scheeres, 1997).

### Example

Distribution of dynamical elevation on asteroid Itokawa. The color map ranges from -25 to 55 m.
