  Amor asteroid - Facts, Information, and Encyclopedia Reference article
The Amor I subgroup consists of Amor asteroids whose semi-major axes are in between Earth and Mars.
Amor I asteroids that have semi-major axes very close to Earth's (such as 1992 JD) can be considered Arjuna asteroids because they have very low eccentricities and thus Earth-like orbits.
Amor IV There are only a few known Amor asteroids whose average distance from the Sun is beyond the asteroid belt.

 NEAR-EARTH ASTEROID TRACKING
*Amors, Apollos, and Atens are the three categories of Near-Earth asteroids (NEAs).
Amor asteroids approach the Earth's orbit from the outside, Apollo asteroids cross the Earth's orbit, and Aten asteroids approach the Earth's orbit from the inside.
Potentially Hazardous asteroids (PHAs) are larger than ~0.2 km (0.1 mile) and approach close enough to present a potential hazard but not a current hazard.

 Main Asteroid Belt
While most asteroids may be only the size of pebbles, 16 asteroids have a diameter of 240 km (150 miles) and Ceres, the largest, has a diameter of about about 914 km (568 miles).
Indeed, if all asteroids down to the size of meter- or yard-sized boulders or less were combined together, the resulting object would measure less than 1,300 to 1,500 km (810 to 930 miles) across, which is less than one third to one half the diameter of the Earth's Moon.
Smaller asteroids, however, should be solid bodies because the shattered fragments of an asteroidal collision should easily escape their feeble gravity and fly off into space instead of settling back on their surface as regolith.

 Amor group
The orbits of Amor asteroids have perihelia between 1.017 AU (Earth’s aphelion distance) and 1.3 AU (Mars’ perihelion distance).
The prototype of the group is the one-km-wide (1221) Amor, discovered in 1932 by Eugène Delaporte.
Amor asteroids vary widely in composition, which indicates they have come from different parts of the main asteroid belt and have been perturbed into their present orbits by either Jupiter or Mars.

 Asteroids
Asteroids, sometimes called "minor planets," are composed of rock, metal, or both.
The main asteroid belt is defined as reaching from 2.2 to 3.3 AU (1 AU is the average distance of the Earth from the Sun).
Since some asteroids were melted, others merely heated, and others left cold, this implies that the distribution of radioactive elements was not uniform in the primeval solar system nebula.

 [No title]
Asteroids are believed to have been jolted by either collision with other objects in space or primary by the gravitational field of the planet Mars or Jupiter.
Asteroids vary in their composition, many are made up of rock and a few are composed of other materials such as metals.
The composition of an asteroid is determined from spectroscopic and measurements in infrared, visible, and ultraviolet parts of the spectrum (Astronomy, Chaisson and McMillan 104).

Most Main Belt asteroids are located between the orbits of Mars and Jupiter (1.8 to 4.0 AU) in a region known as the asteroid belt.
The Trojan asteroids are two groups of asteroids located along the orbital path of Jupiter, 60 degrees ahead and behind the planet.
Asteroids are classified into types according to their albedo and colors or spectra, with the most common types being C, S, and M. C-type asteroids are very dark, with a low albedo of 0.03-0.06, and their spectra are flat, making their color grayish.

 Tiverton A.S. | The Solar System
The surface material of asteroids shares very similar compositions to those of meteorites, so it is believed that meteorites originate from broken-up asteroids.
In turn, asteroids are believed to be the remnants of large planetesimals (similar in size to Mars) which collided early in the Solar System's existence.

Asteroids whose orbits bring them within 1.3 AU (121 million miles/195 million kilometers) of the Sun are called Near-Earth Asteroids (NEA) or Earth-Approaching asteroids.
These asteroids probably came from the main asteroid belt, but were jolted from the belt by collisions or by interactions with other objects' gravitational fields (primarily Jupiter).

 PERMANENT - Transportation - Theoretical
Asteroids have no significant escape velocity or "sea level orbital energy", and can be seen as objects already in orbital space.
The delta-v's for known Earth-crossing asteroids are as low as 60 meters per second (60 m/s), as compared to the Moon's escape velocity of 2,400 m/s.
Many asteroids require a delta-v of much less than 2.2 km/sec, and require only a single lunar gravity assist (not an Earth gravity assist) to be captured, and optionally additional lunar gravity assists to divert the asteroid into a more circular orbit.
