## 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 | 1149 K |
| Host star temperature | 5171 +172 / −130 K |
| Host star mass | 0.83 +0.05 / −0.04 M☉ |
| Host star radius | 0.8 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) | 14.61 |

### 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 | EPIC 212297394 |
| Orbital period | 2.289363 days +0.00023 / −0.00025 |
| Transit midpoint | 2457217.9632 BJD |
| Stars in system | 1 |
| Planets in system | 2 |

### WHEN IT WAS FOUND

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

| Field | Value |
| --- | --- |
| Discovery method | Transit |
| Discovered at | K2 |
