They are believed to have broken away from the main asteroid belt between Mars and Jupiter and are our nearest neighbours in space after the Moon.
Now Pell is back with a new start-up working on space exploration, Moon Express.

The films, showing man in space, on the Moon, on Mars, and the "unknown", fascinated the boy Rutan.
The utterly mundane idea in the video is that we will be doing retail space travel to the moon.
While NASA aim to have a moon base by 2025 other space agencies and companies have expressed an interest in the moon and its potential energy reserves.
The Moon Agreement builds upon the Outer Space Treaty but also says that any natural resources found on the moon are part of "the common heritage of mankind" - in other words, they must be shared.
In many ways these are dreary, dreadfully boring alternatives to moon colonies and space travel.
They floated on spacewalks, planted flags on the moon and built space stations, all playing their role in an international rivalry.
The imagination of scientists has enabled us to travel through outer space and walk on the moon, feats that were once only possible in the realm of myth.
SpaceX was quick to make the point that the ability to carry on despite an engine failure demonstrates a big advantage of multi-engined rockets like the Falcon (Space Shuttles and Saturn V moon rockets could both do something similar).
How much cheaper and easier (if less dramatic) it would have been if Mr Armstrong and Mr Aldrin could simply have stepped into a lift car in space, pressed M for moon, and descended in tranquillity to the sea of that name.
The Obama Administration has canceled plans it inherited to send astronauts back to the Moon, the Space Shuttle is about to retire, and the only near-term human space flight initiative on the books is a handout to rich California businessmen to update old technology.
In 1980, the Nevada-based entrepreneur claimed ownership of the moon after finding what he calls a loophole in the 1967 United Nations Outer Space Treaty, which forbids countries from owning the moon but, according to Hope, does not forbid individuals from owning it.
The moon hung over this space, and it was as if the planet and its satellite were acting as mirror images of each other.
Advances here will inform the more scifi-ish imponderables like a space elevator, and asteroid- or moon-mining.

The Outer Space Treaty provides a legal framework for the international use of space for peaceful purposes, including the moon and other celestial bodies.
Pell founded the company with two others that he met at Singularity University, Naveen Jain, the founder of InfoSpace and Intelius, and Dr. Robert Richards, a founder of International Space University, who is CEO of Moon Express.

Today's commercial rockets can lift only about 10 tons into space, far short of what is needed to enable deep-space exploration returning to the Moon, and later venturing on to Mars the things that are and should be NASA's core mission.

His bold statement might have been more of a publicity drive for Energia rather than a clear commitment to a program, but China, which has committed itself to a space program to land men on the moon by 2017 has also stated its interest in helium-3.
One alternative to Ares, proposed by the United Launch Alliance, a joint venture of Lockheed Martin and Boeing, is to use modified versions of their existing Delta 4 and Atlas 5 rockets both to go to the moon and to resupply the space station, but at lower cost.
It's hard to see any particular reason or purpose in going back to the moon or indeed sending people into space at all.
My company, Moon Express, is focused on the next stage of commercial space beyond low Earth orbit, and is already developing early precursor robotic missions in partnership with NASA to explore the Moon and learn how to develop its resources for the benefit of life on Earth.
FORBES: The Moon is a Natural Platform for Asteroid Mining, Detection and Deflection
It enables the Chinese to build and operate their own space station, establish the technology that is necessary to efficiently send astronauts to the moon and beyond, build and operate fuel depots, and construct vehicles and bases in space.
Last December, one of the last men on the Moon, Harrison Schmitt, told BBC News that he believed Nasa and other government run space agencies were "too inefficient" to be able to send astronauts back to the Moon.
J002E3, as the object was called, actually skimmed past the Moon before whizzing back out into deeper space, disappointing the scientists.

Returning to the moon is an important step for our space program.
CNN: Bush: 'It is time for America to take the next steps' in space
Earth's magnetic field gives the planet and its inhabitants a good measure of protection, but with space agencies seemingly intent on sending astronauts to the Moon and even to Mars in the next few decades, there is a pressing need for a fuller understanding of the Sun's activity.

This confirms a hypothesis from the Hubble Space Telescope, which detected signs of ozone around that Moon.
