You should probably be at least 2-3 feet away from the horse, if you are still worried about it bucking, you should talk to it, make a noise or touch his bottom so he knows where you are.
stand at least 6 feet away
When you are riding on another horse behind a horse, always keep the space of an "imaginary horse" between the two of you. If you are just walking behind a horse, run your hand along their behind to let them know you are there, and if is a bigger horse just make a circle around it.
stand slightly to the side, not directly behind, to avoid being kicked. Keep a safe distance and be aware of the horse's body language to anticipate any sudden movements. Approach the horse calmly and steadily to avoid startling it.
If you get up fairly close you can't get kicked only shoved. Mistake folks make is standing where they believe they're just out of range but anything that weighs 1200lbs and can scratch behind it's ear with a rear hoof has fairly good aim. As long as the horse knows you are there you shouldn't have to stand away from him. Put your hand on his back as you walk around him...to the back especially so he knows where you are.
When walking behind a horse, you should remain a safe distance away from their hindquarters, as they have blind spots where they can't see you. Always approach a horse from the side where they can see you, and speak to them gently to let them know you are there. Avoid making sudden movements or loud noises that could startle them.
at least about 1 and a half metres away from its bak luv horse crazy
Unless you are 6 feet back or at least out of leg range, you shouldn't be standing behind your horse at all. If you must stand behind your horse, always be sure that you are far enough back that if your horse spooked, it couldn't kick you. You should also let the horse know that you are behind it so that there is less chance of it spooking and hurting you. And of course, obviously, don't try to walk behind a horse that you don't know well. Without being familiar with the animal, you would have no idea what to expect from it.
No I wouldn't hug a horse from behind because it could poo or wee on you and also it could run away!
With a familiar and calm horse, it is OK to calmly (but not timidly) go behind while staying close and keeping a hand on top of his hindquarters. With an unfamiliar horse, it is a good idea to stay out of the "kicking radius", about 6 feet away.
When you walk behind I think you are supposed to be extremmly quiet and and stay about 6 ft away from it's hindquarters.
No, you should stand (usually) to the left side, at the horse's shoulder. When leading, you should stand about arms length away so that they won't step on you. (believe me, it's painful) Horses cannot see directly in front of them, so if you suddenly move away from their blind point, they could become startled and run away. The left side of the horse is usually where horses are handled from, so they are more used to being handled from here.
you should stay close to the hindquarters
