Source: https://www.celestialprogramming.com/vsop87-multilang

Demonstrates how to compute the positions of the Earth and Moon using the VSOP87A library. Requires Julian date and Earth-Moon Barycenter positions as input.

```javascript
const jd=2457987.267731481; //TDB time scale
    const t=(jd - 2451545.0) / 365250.0;
    const earth=vsop878a.getEarth(t);
    const emb=vsop87a.getEmb(t);
    const moon=vsop87a.getMoon(earth,emb);
```
