.dot {

  height: 10rpx;
  background-color: #56BD69;
  border-radius: 50%;
  position: absolute;
  top: calc(25% - 5rpx); /* 设置小圆的垂直位置为大圆的中心 */
  left: calc(50% - 5rpx); /* 设置小圆的水平位置为大圆的边缘 */
  transform-origin: 25% 82rpx; /* 将旋转中心设置为小圆自身的中心 */
  animation: rotate 2s linear infinite;
}
 
@keyframes rotate {
  from {
    transform: rotate(0deg) translateX(0); /* 初始位置 */
  }
  to {
    transform: rotate(360deg) translateX(0); /* 绕圆心旋转 */
  }
}

效果：绿圆会围着轨道旋转
