In general, Jupiter is visible in the night sky from anywhere in the world. However, its position in the sky will change throughout the night and throughout the year. For example, in the Northern Hemisphere, Jupiter is currently visible in the southwestern sky in the evening. However, in a few months, it will be visible in the southeastern sky in the morning.
If you are having trouble finding Jupiter, you can use a pair of binoculars or a small telescope. This will help you to magnify the image of Jupiter and make it easier to see.
