Hey do this simple trick:

console.log({star});

Output:

[Log] {star: {id: 1, name: "Arcturus", visualMag: -0.05}}

You can use JSON.stringify

console.log(`${JSON.stringify(test)}`)

When you use an object within template literal, it coerces the object to a string. It looks for a toString method on the object. If it is not found, it will use Object.prototype.toString method which returns "[object Object]".

So, add a toString property to the object.

const star = {
  id: 1,
  name: 'Arcturus',
  visualMag: -0.05,
};

Object.defineProperty(star, "toString", {
  value: function() {
    return JSON.stringify(this)
  }
})

console.log(`${star}`);

Note: You could directly add star.toString = function() { ... }. But, that will add an enumerable property to the object and will be displayed when you log the object directly.
