Characteristics of Five Recently Discovered Gas Exoplanets
Exoplanet designation Mass (Jupiters) Radius (Jupiters) Orbital period (days) Distance from the Sun (parsecs)
TOI-640 b 0.88 1.771 5.003 340
TOI-1601 b 0.99 1.239 5.331 336
TOI-628 b 6.33 1.060 3.409 178
TOI-1478 b 0.85 1.060 10.180 153
TOI-1333 b 2.37 1.396 4.720 200
“Hot Jupiters” are gas planets that have a mass of at least 0.25 Jupiters (meaning that their mass is at least 25% of that of Jupiter) and an orbital period of less than 10 days (meaning that they complete one orbit around their star in less than 10 days), while “warm Jupiters” are gas planets that meet the same mass criterion but have orbital periods of more than 10 days. In 2021, Michigan State University astronomer Joseph Rodriguez and colleagues announced the discovery of five new gas exoplanets and asserted that four are hot Jupiters and one is a warm Jupiter.

 

Which choice best describes data from the table that support Rodriguez and colleagues' assertion?
Difficulty: Medium
A: 

None of the planets have an orbital period of more than 10 days, and TOI-628 b has a mass of 6.33 Jupiters.

B: 

TOI-1478 b has an orbital period of 153 days, and the masses of all the planets range from 0.85 to 6.33 Jupiters.

C: 

All the planets have a radius between 1.060 and 1.771 Jupiters, and only TOI-1333 b has an orbital period of more than 10 days.

D: 

Each of the planets has a mass greater than 0.25 Jupiters, and all except for TOI-1478 b have an orbital period of less than 10 days.
