IEOs

IEOs are Inner Earth Objects, or asterois with orbits which lie enteirely in the Earth orbit. These objects can occasionally come very close to our planet, but they are very difficult to detect from the ground because this particular observing geometry places them at small angular distances from the Sun for most of the time, making them invisible against the bright sky background. It is exactly this difficulty that, until now, has prevented observers from discovering IEOs, although their presence in the inner regions of the Solar System has been predicted by dynamical studies and is generally accepted by scientists.
