Gaia by British artist Luke Jerram - who also created the work Museum of the Moon - measures 7m (30ft) in diameter and features detailed Nasa imagery of the Earth's surface.
The suspended artwork gives visitors to the science museum a sense of what the planet looks like from space.
Mr Jarram said: "When you're in space looking down on the planet you realise just how fragile we all are and how we are connected as we are all living on this thin little ledge of a planet and we're in a vulnerable state really."
The artwork took about six months to create with the imagery printed on to fabric, stitched together like a balloon and illuminated from the inside.
Mr Jerram said he hoped it would encourage families to act on climate change.
"We've only got one planet Earth and we've got to look after it," he said.
