<h2>
Mercury, Neptune, and Jupiter </h2>
Explanation:
- Mercury has the largest semimajor axis that is 5.791 x 107 in km.
- Mercury is the planet with the fastest speed, which has an average orbital speed around the sun for about 47.87 km/s.
- Neptune has the longest orbital speed around the sun of any planet in the Solar System which is equivalent to 164.8 years (or 60,182 Earth days)
- Jupiter has the largest eccentricity.
Hence, the answer is Mercury, Neptune, and Jupiter respectively.
Explanation:
For a circular orbit v=
with G = 6.6742 × 
Given m = 6.42 x 10^23 kg and r=9.38 x 10^6 m
=> v = 2137.3 m/s
I hope this is the correct way to solve
