Orbit Data For All Known Asteroids In MPC Database

Context

Asteroids have always been one of the most studied celestial bodies in the sky. The story of their creation to the trajectory they follow is nothing but amazing. This dataset is nothing more than me scavenging the web for latest asteroid related data. This dataset is suitable for beginners who are exploring the different techniques in Machine Learning. A reasonably high accuracy can be achieved by choosing the right model.

Content

The dataset presents a basic Multi Class Classification problem. One has to classify the orbit of the Asteroid into one of the following types:-
• Atira
• Aten
• Apollo
• Amor
• Object with perihelion distance < 1.665 AU
• Hungaria
• MBA
• Phocaea
• Hilda
• Jupiter Trojan
• Distant Object

The other columns are described below:-

Name -----string Name----- if the asteroid has received one

Number -----string Number------ if the asteroid has received one; this is theasteroid's permanent designation

Principal_desig -----string------ Principal provisional designation (if it exists)

Other_desigs -----string -----Other provisional designations (if they exist)

H -----float -----Absolute magnitude, H

G -----float -----Slope parameter, G

Epoch----- float----- Epoch of the orbit (Julian Date)

a -----float -----Semimajor axis, a (AU)

e -----float ------Orbital eccentricity, e

i -----float----- Inclination to the ecliptic, J2000.0 (degrees)

Node -----float -----Longitude of the ascending node, ☊, J2000.0 (degrees)

Peri -----float -----Argument of perihelion, ω, J2000.0 (degrees)

M ----float -----Mean anomaly, M, at the epoch (degrees)

n -----float----- Mean daily motion, n (degrees/day)

U -----string -----Uncertainty parameter, U

Ref -----string -----Reference

Num_obs----- integer -----Number of observations

Num_opps -----integer -----Number of oppositions

Arc_years -----string----- Only present for multi-opposition orbits (year of first observation – year of last observation)

Arc_length----- integer----- Only present for 1-opposition orbits (days)

rms -----float----- r.m.s. residual

Perturbers -----string----- Coarse indicator of perturbers used in orbit computation

Perturbers_2 -----string -----Precise indicator of perturbers used in orbit computation

Last_obs -----string----- Date of last observation included in orbit solution (YYYY-MM-DD format)

Hex_flags----- string -----4-hexdigit flags

Computer----- string----- Name of orbit computer (be it a person or machine)

NEO_flag------ integer -----Value = 1 if flag raised, otherwise keyword is absent

One km_NEO_flag------ integer----- Value = 1 if flag raised, otherwise keyword is absent

PHA_flag----- integer -----Value = 1 if flag raised, otherwise keyword is absent

One opposition_object_flag----- integer----- Value = 1 if flag raised, otherwise keyword is absent

Critical list numbered object_flag -----integer -----Value = 1 if flag raised, otherwise keyword is absent

Perihelion_dist----- float----- Perihelion distance (AU)

Aphelion_dist----- float---- Aphelion distance (AU)

Semilatus_rectum -----float -----Semilatus rectum distance (AU)

Orbital_period---- float----- Orbital period (years)

Synodic_period----- float----- Synodic period (years)
