The other contributions of Bhāskara I was on Mahābhāskarīya and Laghubhāskarīya[3] on the astronomy.
Mahābhāskarīya deals with the following topics .
- Mean positions of the planets
- True positions and true velocities of the planets and their applications
- Directions , time and place
- Computation and graphical representation of the eclipses
- Conjunction of a planet with a star
The language of Mahābhāskarīya is simple and is meant to be easily understandable.
Mahābhāskarīya is the only available work on Hindu Astronomy which explains the motion of the planets with the help of the epicyclic theory and eccentric theory.
Laghubhāskarīya is a revised and abridged edition of Mahābhāskarīya . It was written for younger and immature students of astronomy. Laghubhāskarīya deals with the following topics .
- Chapter 1 - Calculation of the mean longitudes
- Chapter 2 - Calculation of the true longitudes, the Pañcāṅg
- Chapter 3 - Directions, place and time
- Chapter 4 - Eclipse of the moon
- Chapter 5 Eclipse of the sun
- Chapter 6 - Heliacal visibility and phases of the moon, elevation of the Moon's horns , and moonrise
