In an orbit, the second focal point refers to the other focus of the elliptical shape that the orbiting body follows. In a standard elliptical orbit, one focus is occupied by the central body (like a star or planet), while the second focus is empty and does not contain any physical object. The gravitational pull of the central body governs the motion of the orbiting body, creating the elliptical path. This concept is derived from Kepler's laws of planetary motion.

Focus or the focal point.
If you shine a parallel (ie unfocussed) beam of light perpendicular to a convex lens it will focus to a point on the other side. That place is called the focal point of the lens. Its distance to the lens is called the focal length.
The highest point in an orbit is called the apogee. It is the point where the spacecraft is farthest from the body it is orbiting.
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
Earth's orbit is an ellipse; the Sun is at one of the ellipses focal points. (The other focal point has no astronomical significance.)
That applies to all planets. Planets go around the Sun in elipses - the Sun is at one of the focal point of the elipse. The focal point is not the center.

focal length of the lens
The distance from a lens to the focal point is called the focal length.
Focal Point:The distance from the Lens to the Focal Point is called the Focal Point.
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
The focal point of a circle is the center.
The distance from the center of a mirror to the focal point is called the focal length.
The distance from the center of a mirror to the focal point is called the focal length.
In art a composition's focal point is actually called the focal point. There may be multiple focal points, in which case the main one is the focal point and the others are secondary focal points. You can recognize the focal point because it is somehow set apart from the rest of the composition.
Focus (only at the focal point if the incoming rays are all parallel to the axis).
