- •
We search SDSS image archive for near-Earth (NEA) and Mars-crosser (MC) asteroids.
- •
We report on the taxonomic classification of 206 NEA and 776 MC.
- •
We study NEA source regions and confirm the inner main belt as a major source.
- •
We develop a force model on surface grain and study planetary encounters.
- •
The fresher surfaces have statistically more encounters with Venus and Earth.
