# HIP 65407 c

HIP 65407 c is a gas giant in the constellation [Canes Venatici](https://spacecatalog.org/constellation/canes-venatici), 201.5 ly from Earth. It orbits HIP 65407 at a mean distance of 0.316 AU. It has a mass of 0.78 M♃ and a radius of 1.24 R♃ · 88 656 km. It was discovered in 2016.

## At a glance

- **WHAT IT IS:** Gas giant
- **HOW FAR:** 201.5 ly — The light arriving now left it that long ago.
- **HOW BIG:** 1.24 R♃ · 88 656 km — Its radius: half the width across.
- **WHERE TO LOOK:** [Canes Venatici](https://spacecatalog.org/constellation/canes-venatici) — The patch of sky it sits in, as seen from Earth.

## 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 | 457.04 K |
| Host star spectral type | K0 |
| Host star temperature | 5460 ±50 K |
| Host star mass | 0.93 ±0.07 M☉ |
| Host star radius | 0.952252 +0.011 / −0.028 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) | 9.38 |

### 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 | HIP 65407 |
| Orbital period | 67.3 days |
| Eccentricity | 0.12 ±0.04 |
| Argument of periastron | −19 ±25° |
| Periastron epoch | 2457047.0000 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 |
