SVG path animation not as expected - html

Question

The moon needs to move in that path same as the one with id of trajectory around the planet. But it is moving randomly (as if it's celebrating 4/20).
Please find the attached code.
.moon {
offset-path: path('m159.39 54.867a71.83 20.37 0 0 1-71.83 20.37 71.83 20.37 0 0 1-71.83-20.37 71.83 20.37 0 0 1 71.83-20.37 71.83 20.37 0 0 1 71.83 20.37z');
animation: revolve 10s 1s infinite ease-in-out forwards;
}
#keyframes revolve {
from {
offset-distance: 0%;
}
to {
offset-distance: 100%;
}
}

Answer 1

offset-path is not yet supported enough by browsers caniuse.com
To realize the moon moving along a trajectory, consider using animateMotion
<svg width="169.31" height="115.66" viewBox="0 0 169.31 115.66">
<circle cx="87.56" cy="54.867" r="45.855" fill="#ff4141" />
<circle class="moon" cx="0" cy="0" r="8.092" fill="#ff9900" >
<animateMotion begin="0s"
dur="12s" repeatCount="3" fill="freeze" restart="whenNotActive" >>
<mpath xlink:href="#trajectory" />
</animateMotion>
</circle>
<path
id="trajectory"
d="m18.051 54.867c1.9043-12.055 45.047-20.455 69.073-20.601 25.048-0.15208 64.422 2.9195 72.266 20.601-6.7091 16.516-45.54 20.472-69.791 20.552-24.814 0.082685-67.739-4.5793-71.548-20.552z"
fill="none" stroke-width=".5px" stroke="#000000" />
