A type stars are bigger and hotter than our Sun, A type main-sequence star mass is around 1.4 to 2.1 solar masses and size 1.6 to 2.4 solar radii. In this 3d visualization we will see the size of A type main sequence and giant stars compared to our Sun which is a G-type main-sequence star 4.6 billion years old.

Kepler-444 A is a K-type old metal poor star 119 light-years away. The planet Kepler-444c and d are small planets half the size of planet Earth. Their orbital period is under 7 days so they are short period sub earth sized planet. The Secondary stars Kepler-444B and Kepler-444C are binary pair spectral type of "M" 29% and 25% mass of Sun, 0.3 AUs apart from each other, orbiting Primary A in 198 years in a high eccentric orbit. -------------------------------------------------------------------------------------------------------------------------------------------------------------- In this video we will see the Ancient star system Kepler-444 c and d exoplanets in Space Engine. I made other two videos related to Kepler-444e ,b and f planets in space engine.
