ASTEROID-433 EROS
It is a type of S-type asteroid. It is the first discovered and second-largest object found near the Earth whose mean diameter is about 16.8 kilometres. It is the first asteroid to found travel in the mainly inside the orbits of Mars and also the first asteroid to study from orbit. It was named after the name of EROS, a god from Greek mythology[also known as Venus].

| 433-EROS |
It belongs to a member of the group called Amor or Earth-Approaching, can pass within 22 million km of Earth. It was the first asteroid that displays variation in its brightness. The first spacecraft flew nearby this asteroid was the NEAR [ Near Earth Asteroid Rendezvous – Shoemaker] renamed after its 1996 launch in honour of planetary scientist Eugene Shoemaker, on 23rd December 1998, at a distance of approximately 2400 km. This space probe Eros collected a full year of data on its surface composition, topography, mass, gravity field, internal structure, and other properties before touching down gently on its surface. Its rotation period is about 5.27 hours. It is elongated in size and its size is considered to be the twice of Manhattan Island situated in New York's City.
WORTH of 433-EROS :
Assuming that 433-Eros contains only 5% iron, there are 22.5 billions tons of platinum on the asteroid. The current price for platinum is about $750 per troy ounce. It contains 20 billion tonnes of aluminium and many more that are rare on EARTH.
FORMATION of EROS :
It is made up of the same materials as chondrites, primitive meteorites found on Earth and believed to be leftover from the formation of the planets billions of years ago.
Do EROS will heat the Earth :
There is some bad news, calculated by European mathematicians. There seems to be a significant chance that within the next 1.14 million years, an asteroid named 433 Eros could hit Earth, with dire results for the human race and most other species. Little 433 Eros is not on most lists of potential planetary catastrophes
