Dataset Description

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

Name - name of the asteroid.

Number - Permanent designation of the asteroid

Principal_desig - Principal provisional designation (if it exists)

Other_desigs - Other provisional designations (if they exist)

H - Absolute magnitude

G - Slope parameter

Epoch - Epoch of the orbit (Julian Date)

a - Semimajor axis, a (AU)

e - Orbital eccentricity, e

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

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

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

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

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 oppositionobjectflag----- 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)
