Among di giant planets for di Solar System, Neptune na di most dense. Neptune na 17 times di mass of Earth and e slightly more massive pass hin near-twin Uranus, wey na 15 times di mass of Earth and slightly bigger pass Neptune. Neptune dey orbit di Sun once every 164.8 years for an average distance of 30.1 astronomical units (4.50×109 km). Dem name am after di Roman god of di sea, hin astronomical symbol na ♆, a stylised version of di god Neptune's trident.

Neptune no dey visible to di unaided eye and e be di only planet for di Solar System wey dem find by mathematical prediction instead of empirical observation. Unexpected changes for di orbit of Uranus make Alexis Bouvard reason say hin orbit dey subject to gravitational perturbation by an unknown planet. Neptune later dey observed with telescope on 23 September 1846 by Johann Galle within one degree of di position wey Urbain Le Verrier predict. Hin largest moon, Triton, later dey discovered, even though none of di planet's remaining 14 moons dey located telescopically until di 20th century. Di planet's distance from Earth make am get very small apparent size, wey make am hard to study with Earth-based telescopes. Voyager 2 visit Neptune when e fly by di planet on 25 August 1989. Di arrival of Hubble Space Telescope and large ground-based telescopes with adaptive optics don recently allow for additional detailed observations from afar.

Answer di following questions:
1. Where Neptune name come from?
2. Wetin hin astronomical design suppose mean?
3. E discover by accident with telescope?
4. How e take find am?
5. Who do am?
6. Wetin make am reason say another planet dey out there?
7. How many other planets dem discover dis way?
8. Who first see am through telescope?
9. E dey close to where dem think say e go dey?
10. E get any moons?
11. Pass ten?
12. Which one be di biggest?
13. E easy to see di planet through telescope?
14. Any man-made objects don reach close to am?
15. Which one?
16. Neptune na di seventh planet from di sun?
17. E be fairly dense planet?
18. How many Earth years be one Neptune year?
19. E get similar planet like Neptune?
20. Which one?
