Pulsating floating red orb flies over home.

I was not the first one to see this light object.  My mother went outside to hang some clothes when I heard her call me out.  She was calling me in a hurried manor.  I went outside just in time to see this orb floating directly above trees in our backyard and it floated over our home.
We watched it together for close to 5 minutes as it slowly floated by. It was an orange/red color.  Pulsating from low brightness to high brightness.  If I had to compare it to something it'd have to be like how a flare would look.
The orb came up low over trees in our back yard, flew over our home and ascended into the dark sky.  We watched it for about 5 mins before we couldn't see it anymore.  There were planes in the area flying above.  Our dog was with us as we stood out watching and it whimpered as if frightened.  It may be due to the light orb.
