- 2014 RC: This asteroid made a close approach to Earth in 2014, passing by at a distance of about one-tenth the distance from Earth to the Moon.
- 2004 FH: Classified as a near-Earth asteroid, 2004 FH passed by Earth in 2004 at a remarkably close distance, around 43,000 kilometers.
- 99942 Apophis: A notorious asteroid known for its close approaches to Earth, Apophis caused a stir due to initial concerns of a potential impact in the future (later ruled out).
- 69230 Hermes: Discovered in 1937, Hermes is notable for having an exceptionally eccentric orbit, crossing the paths of both Earth and Venus.
- (29075) 1950 DA: Considered a potentially hazardous asteroid, 1950 DA has a small chance of colliding with Earth in the distant future, around the year 2880.
- 4769 Castalia: This asteroid is an Apollo asteroid, meaning it crosses Earth’s orbit, and it was the first such object to be discovered by radar.
- 719 Albert: Named after Albert Einstein, this asteroid was discovered in 1911 and is part of the Flora family of asteroids.
- 3200 Phaethon: This asteroid is the source of the Geminid meteor shower, one of the most intense and reliable meteor showers observed on Earth.
- 433 Eros: Visited by the NEAR Shoemaker spacecraft, Eros is one of the largest near-Earth asteroids and provided valuable data about asteroid composition.
- 243 Ida: This asteroid gained attention when the Galileo spacecraft discovered a moon, Dactyl, orbiting it, making Ida the first asteroid found to have a moon.
- 323 Brucia: A member of the Eunomia asteroid family, Brucia was discovered in 1892 and is named after Catherine Wolfe Bruce, a philanthropist who supported astronomy.
- 1902 Shaposhnikov: Named after Russian astronomer Ivan Ivanovich Shaposhnikov, this asteroid belongs to the Eos family.
- 20 Massalia: One of the first asteroids to be discovered, Massalia was found in 1852 and is named after the ancient Greek city of Marseille.
- 45 Eugenia: This asteroid is known for its unique shape, resembling a dumbbell or peanut, and was the first asteroid confirmed to have a moon.
- 87 Sylvia: Sylvia is a triple asteroid system, consisting of a central asteroid orbited by two smaller moons named Romulus and Remus.
- 52 Europa: Europa is a member of the large Themis asteroid family and was discovered in 1858.
- 10 Hygiea: Hygiea is the fourth-largest asteroid by mass and was named after the Greek goddess of health.
- 2 Pallas: Pallas is one of the largest asteroids in the Solar System and was the second to be discovered after Ceres.
- 4 Vesta: Vesta is the second-largest asteroid and is considered a protoplanet, showcasing geological features such as impact craters and a distinctive surface composition.
- Ceres: Ceres is the largest object in the asteroid belt between Mars and Jupiter and is classified as a dwarf planet. It was visited by the Dawn spacecraft, providing detailed insights into its composition and geological features.
