## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Equilibrium temperature | 863 K |
| Host star temperature | 6410 ±183 K |
| Host star mass | 1.406 +0.074 / −0.086 M☉ |
| Host star radius | 2.136 ±0.096 R☉ |

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Host star apparent magnitude (V) | 11.29 |

### THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.

| Field | Value |
| --- | --- |
| Host star | TIC 147027702 |
| Orbital period | 44.40523 days ±0.00013 |
| Eccentricity | 0.127 +0.055 / −0.048 |
| Inclination | 89.52 +0.32 / −0.3° |
| Argument of periastron | 223.7 +23 / −17° |
| Transit midpoint | 2458550.7314 BJD |
| Stars in system | 1 |
| Planets in system | 1 |

### WHEN IT WAS FOUND

Who first saw it, from where, and by what method.

| Field | Value |
| --- | --- |
| Discovery method | Transit |
| Discovered at | Transiting Exoplanet Survey Satellite (TESS) |
