Mars Asteroid Observation

The dataset comprises approximately 18000 data entries containing 26 columns of characteristics of the asteroid. You can use the dataset to accurately predict the observational days (named as 'data_arc' in the data) required to capture the characteristics of the asteroid crossing by the planet, Mars. A brief description of the dataset is provided in the below section.

Columns

Column features are described in the following format -

short info (unit of the feature); an additional description.

Note: Numerical values refer to no specific unit and should be considered a number describing the particular feature of the asteroid.

• ID - unique ID of the asteroid (the first column of the dataset); required for final submission
• full_name - Contains the complete designation or name of celestial objects in the dataset, serving as a unique identifier.
• sigma_e - standard deviation of the eccentricity observed over previous years (numerical value)
• sigma_a - standard deviation of the semi-major axis observed over previous years (numerical value)
• sigma_i - standard deviation of the inclination observed over previous years (numerical value)
• sigma_om - standard deviation of the longitude of ascending node observed over previous years (numerical value)
• sigma_w - standard deviation of the argument of perihelion observed over previous years (numerical value)
• sigma_ma - standard deviation of the mean anomaly observed over previous years (numerical value)
• sigma_ad - standard deviation of the Aphelion distance observed over previous years (numerical value)
• sigma_n - standard deviation of the count of observations used over previous years (numerical value)
• sigma_tp - standard deviation of the time of perihelion passage observed over previous years (numerical value)
• sigma_per - standard deviation of the sidereal orbital period observed over previous years (numerical value)
• a - Semi-major axis (au); Represents the size of the object's orbit around the Sun in astronomical units (au).
• e - Eccentricity(numerical value); Indicates how elliptical or circular the object's orbit is, with values close to 1 indicating high eccentricity.
• i - Inclination (degrees); Angle describing the tilt of the object's orbit relative to the solar system's plane.
• om - Longitude of the ascending node(degrees); Specifies the position of the object's orbital ascending node.
• w - Argument of perihelion(numerical value); Defines the angle between perihelion and the ascending node.
• ad - Aphelion distance (au); Farthest distance between the object and the Sun during its orbit, measured in astronomical units.
• q - Perihelion distance (au); Closest distance between the object and the Sun during its orbit, measured in astronomical units.
• per_y - Orbital period (year); Time taken for the object to complete one orbit around the Sun, measured in years.
• n_obs_used - Number of observations used(numerical value); Number of observational data points used to calculate the object's orbital parameters.
• ma - mean anomaly (degrees); a fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis.
• condition_code - Orbit condition code (numerical value); Code indicating the quality and reliability of the object's orbital data.
• H - Absolute Magnitude parameter (numerical value); Measure of the object's intrinsic brightness or reflectivity, indicating its size and composition.
• epoch_mjd - the epoch of osculation in modified Julian Day Form(numerical value); the instant of time at which the position and velocity vectors were used to calculate the characteristics.

Output (Target label)

• data_arc - Data arc-span (days); Duration over which observational data has been collected for the object, measured in days.
