It's Newton's first law of motion: "An oject in motion will stay in motion (with the same velocity) until an outside force acts upon it and an object at rest will stay at rest until an outside force acts upon it."

No. The mass of any object is considered to be an intrinsic constant property, i.e. it's a characteristic of the object and it doesn't change, no matter where the object goes or what happens to it. The weight of the object may change, because that's just the force of gravity caused by whatever large body the object happens to be near, like the earth or moon.
Both it's mass and the force of gravity acting on it
away from the observer.
Sun's gravitational pull keeps the earth in an elliptical orbit around it.If there would be no gravitational pull of sun on earth than the earth would start moving in a straight line at an angle of 90 degree like a tangent to a circle.
INERTIA. This is not an 'ability', but rather a PROPERTY of Matter.- Newtons First Law, "inertia", the propety of matter defined by a still object's tendency to stay at rest, and a moving object's tendency to keep moving at the same velocity.
Momentum
The amount of matter in an object is the fundamental property of the object. This is matter to weight.
The amount of matter in an object is the fundamental property of the object. This is matter to weight.
an object that is not moving can be in equilibrum. an object moving at a steady speed in a straight line can also be equilibrum.
Inertia
It is called inertia.

It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
The answer to the question seems to be clearly given within the question. You have said that the object " ... is moving ... " in a straight line. Therefore we conclude that if you have been honest with us, then the object is certainly in motion.
If an object is moving away from you and there are no forces acting on it,then it continues moving in a straight line at constant speed.
The object continues moving in a straight line at its current speed.
